Introduction
3200T: 2-Port Processor Card
3201: 4-Port Processor Card

5
The 3200T/3201 Processor cards are capable of solving user application logic, communicating to host
applications, and/or communicating with I/O cards in the chassis. The system configuration determines how the
card functions. The 3200T/3201 Processor can be configured single, dual redundant, triple redundant, quad
redundant or distributed.
Two indicator LEDs are located near the top of the front panel. The left LED indicator displays the overall
health status of the card. If this LED is on, the card is functioning normally; if it is off, the card has detected an
error or is offline. The right indicator LED indicates the node processor status as shown in Figure 1.

Figure 1: 3200T/3201 Processor Front Panel
If the left LED on the top is off and the right LED on the top is on, then the windowed watchdog timer on the
node processor is expired due to an error (node is running faster or slower, 500 ms, than it is configured in
WWDT), Board/CPU temperature was higher than temperature defined in node processor shutdown object, the
voltage monitor has caused the card to latch reset or 2-0 Tolerance Time defined in node processor shutdown
object has expired. 2-0 Tolerance time should be configured only when you operate with redundant Node
Processors. Setting a non-zero value (between 0.01 seconds and 327.67 seconds) enables the system to start
the Elapsed timer; when it is Latched true in redundant mode (more than one node processor had come on line
and operational) and only one Node Processor is left online and operational. If successful redundant Node
Processor operation is not established within the 2-0 Tolerance Time, the remaining Node Processor CPU is
turned off, effectively de-energizing all outputs and putting the SIS into a safe state. It is necessary to de-
energize node processor card to put card in normal function again.
Each Ethernet port on the card has two LED’s: The top LED turns on whenever there is transmit / receive
activity. The bottom LED on the Ethernet port indicates the link status: If the link is functioning normally, it will
turn on.

of this battery is five (5) years. Replace this battery only with an agency-
approved battery of the same voltage and capacity (3V, 180 mAh). Two
recommended replacements are:
Panasonic part number BR 2032
Varta part number CR 2032
WARNING! If you replace the battery with an incorrect type, it may
explode.
Do not dispose of batteries in the trash. Dispose of batteries according to
local regulations.
Please recycle according to local regulations.
Programming Tools: NetArrays Developer Studio
Programming Languages: Flow Charts, Objects, Structured Text, C/C++, Fuzzy Logic, Ladder Logic
Processor Utilization: Processor can be configured for cyclic execution from 1ms to 25ms.
Processor utilization is measured via Node Info Object, which reports the
reserve time in each execution cycle.
Processing of I/O: The 3200T/3201 Processor communicates each scan cycle with the
Chassis I/O. Inputs from the modules are processed in the user
application program after two scan cycles. Computational results of the
user application program are sent back to the modules to activate the
outputs.
Self-Tests and Diagnostics: Processor performs a Power-On-Self-Test (POST) upon cold startup or if
instructed by the Node Shutdown object. POST includes comprehensive
memory tests and verification of the onboard peripherals. Runtime
diagnostics tests CPU, registers and allocated memory.

Software Configuration
Editing the Configuration File
The 3200T/3201 Processor must be configured correctly, before the user application program is fully deployed.
The 3200T/3201 Processor is shipped either with a default IP address (89.89.89.89) or as marked on the
chassis.
1. Ensure that redundant 3200T/3201 Processors are turned off.
2. Use the Project Tag Database Manager (PTDBM.exe) and configure the default IP or the factory
configured IP address(es).
3. Ensure that the PC’s network interface is configured in the same IP domain as the 3200T/3201
Processor. Issue a ping command from the PC to the configured IP address to verify connectivity. If
there is no response from the controller, set DIP SW2-1 on the 3200T/3201 Processor card (see Figure
2) in the ON position; remove Ethernet cable on port J2; and turn on the 3200T/3201 Processor. This
will put the 3200T/3201 Processor into Bootloader mode, which stops executing any user application
logic and communicates for configuration changes over the default IP address 89.89.89.89.
4. Run the Node Configuration program (RTPNC.exe) and select the device created in step 2.
5. Right click on the file name VIK2K1.CFG and select Upload from the pull-down menu. (Uploads and
downloads are password protected, so you will need the download password to upload the configuration
file. The default password is “rtp”).
6. Configure the Node Processor parameters and click the Download button to write the configuration to
the Node Processor. Enter the password when prompted (Uploads and downloads are password
protected, so you will need the download password to download the configuration file. The default
password is “rtp”).

17
7. Reconnect all Ethernet cables and set DIP SW2-1 on the 3200T/3201 Processor card (see Figure 2)
back to its OFF position (if changed in step 3) and power-cycle the 3200T/3201 Processor.
8. Download the user application program (with the correct I/O Configuration) from NetArrays. From
the Device Status window, verify that the user application program is running.
9. For redundant configurations reconnect the Ethernet cables and turn the power on at the “B”, “C” and
“D” Node Processors. The configuration parameters will be transferred to the redundant processors.
Configuration Parameters
Use the Device Configuration Editor to change the configuration parameters from their default settings. To
change an entry, move the mouse pointer to the parameter, select it, and type the new value. When finished,
click on the Download button to write the configuration file to the target device. The VIK2K1.CFG configuration
file parameters are:
ipaddress, ipaddress_b, ipaddress_c, ipaddress_d, ipaddress_e

18
These IP address parameters specify the Ethernet IP address used to communicate with the node
processor card(s). The format of an IP address is nnn.nnn.nnn.nnn, where nnn can be any number
from 0 to 255. The Ethernet IP address must match the IP address assigned to the device in the
NetArrays Project Tag Database Manager (Default address: 89.89.89.89). Enter the IP address
specified in the device configuration for the target node, otherwise leave default value 0.0.0.0. Please
note that the IP address cannot contain leading zeros: e.g. 089.089.089.120 is not a valid IP address.
These entries define up to five IP addresses:
For RTP3200S and RTP3200D systems:
Configure ipaddress and ipaddress_b.
Note! For RTP3200S system, use PTDBM application and configure node as Single and define
IP Address and IP Address2 for redundant host communication.
For RTP3200T systems:
Configure ipaddress for node processor A, ipaddress_b for node processor B and ipaddress_c
for node processor C.
For RTP3200Q systems:
Configure ipaddress for node processor A, ipaddress_b for node processor B, ipaddress_c for
node processor C and ipaddress_d for node processor D.
ipaddress_e is used for the 3200T/3201 Processors in the system that exceed the configured
redundancy.
If the IP address parameter for a node processor is not configured, and this node processor is inserted
into the RTP3200 system, then the following display status message will be printed:
Node Processor %s –Requires Configuration File IPAddress
where %s is the newly inserted new node processor B, C or D, which is not configured in the
configuration file. Likewise, if the user application program has less node processors configured than
what is physically configured then the following display status message will be generated:
Node Processor %s –Requires I/O Configuration Node Update
where %s is the newly inserted new node processor B, C or D, which is not configured in the NetArrays
user application program file’s IOC page.
Subnetmask
The subnetmask parameter specifies the subnet mask to the processor card. The format of the subnet
mask is nnn.nnn.nnn.nnn, where nnn can be any number from 0 to 255 (Default value is 255.0.0.0,
which is suitable for an internal or private network).
Max Scan cycle (100 µs)
The max scan cycle is the maximum scan cycle length before the node will timeout in 100 microsecond
increments. Default value is 650 or 65 milliseconds.
Nodenum
A node number is required for Peer-to-Peer communications in a multiple-node configuration. Node
numbers can range from 0 to 99. Each peer node must have a unique node number from 1 to 99. A
node number of 0 (zero) disables Peer-to-Peer communications for the node (Default value is 0). The
assigned node numbers are then used for the creation of peer variables in the NetArrays project
program.
Maxconn
The maxconn parameter specifies the maximum number of TCP/IP network connections (sockets)
allowed. The maximum value is 215 (Default value is 50).

19
For example, each host that connects to this node consumes one connection, each peer node that
receives data from this node consumes one connection, and each peer node that sends data to this
node consumes one connection. The total number of all these connections must not exceed the value
entered for this parameter.
Peer alltime(s)
To reduce network traffic during normal peer-to-peer operation across domains, only those peer
variables that changed are sent to nodes in other domains. However, the processor periodically sends
all of its peer variables to the other nodes in other domains. The peer_alltime parameter specifies how
often these “all peer variable” transfers occur (Valid range: 0 to 21474836 in 1 second increments –
Default value: every 60 seconds).
Domain Peer alltime(s)
To reduce network traffic during normal peer-to-peer operation within a domain, only those peer
variables that changed are sent to the other nodes in the domain. However, the processor periodically
sends all of its domain peer variables to the other nodes in the domain. The domain_peer_alltime
parameter specifies how often these “all domain peer variable” transfers occur (Valid range: 0 to
21474836 in 1 second increments –Default value: every 3600 seconds).
Ip route
The IP route parameter is required if the node must respond to communications from a
host located on another network. If all the nodes and hosts reside on the same network, this parameter
is not required and should be left at its default value.
The format of an IP route is composed of three elements, each separated by a space as follows:
destination mask gateway. The format of each of the three elements is
nnn.nnn.nnn.nnn, where nnn is a number from 0 to 255. Up to five IP routes may be entered in this
parameter, each separated from the other by a space. There are three types of IP routes that may be
added in this parameter: host routes, network routes, and a default route. The routes specify networks
(destination AND mask) that must be different than the one containing the RTP target node as specified
in the ipaddress parameter. Be careful not to enter the ipaddress into the ip route parameter
The default route is the simplest means to access a host on another network. It takes the
form: 0.0.0.0 0.0.0.0 gateway, where gateway is IP address of the gateway computer, or
router, that connects the target node’s network to the network where the host resides.
(The destination and mask must be 0.0.0.0.) Note that only one default route is allowed in the IP route
parameter. Example: 0.0.0.0 0.0.0.0 10.100.100.65 triplet entry in the ip route parameter to reach all
other networks. In this example, the gateway 10.100.100.65 is in the same network as the RTP target
node, as specified in ipaddress parameter (e.g. 10.10.10.64).
A host route defines one specific host on another network. It takes the form: destination
255.255.255.255 gateway, where destination is the IP address of the host and gateway is the IP
address of the gateway computer connecting the two networks. (The mask must be 255.255.255.255.)
A network route specifies a route to a subnet of hosts which is a route that will match multiple IP
addresses. It takes the form: destination mask gateway, where destination is the IP address of the
host, mask is a subnet mask that masks all but the intended range of addresses, and gateway is the IP
address of the gateway computer connecting the two networks. For example, the network route
192.200.100.0 255.255.255.0 gateway would provide valid routes to all hosts with IP addresses
between 192.200.100.1 and 192.200.100.255 on the network connected by the gateway, or router,
defined by gateway.
The gateway, or router, must have an IP address (gateway) that is within the same network as specified
in the ipaddress configuration parameter.
Note: Do not change the ip_route parameter for communications in Safety Instrumented Systems.
Safety-critical communication messages (e.g. peer-to-peer messages) should not be routed.

Maxpgm
The maxpgm parameter specifies the maximum amount of memory (in bytes) allocated for the project
program. The default value is 1,843,712 bytes (Valid range: 307,712 to 4,096,512). You must allocate
sufficient memory for the project program. If the project program is too large, an error message is
generated during the attempted download.
Udl mem
The udl_mem parameter specifies the amount of memory (in kilobytes) allocated for the UDL files (file
extension .UDL) included with the project program in the node processor. The value specified must be
as large as, or larger than the actual UDLs (Default value: 512 kilobytes –Valid range: 0 to 1500
kilobytes).
Output Disable Type
This entry, if exists, determines the action taken by a non-safety I/O node if its Chassis Processor
stops receiving valid output messages from the processor card. Valid entries are 0 and 1. If set to 0, the
Chassis Processor will disable all I/O card outputs (zero / OFF / de-energize). If set to 1, it will use the
“default” parameter of the programmed I/O card output channel. The default value is 0.
Host activity max
This entry sets the threshold in recognizing a flood condition on the host network. The default setting is
300 interrupts per scan cycle and is based on 25 ms scan cycle setting. This parameter is scaled
automatically with the scan cycle setting, for example: If the scan cycle is at 10 milliseconds, then this
parameter is scaled internally to 240 and if the scan cycle setting is 5 milliseconds, then this parameter
is scaled to 180 internally. Setting this parameter to a large number (e.g. 1000), disables checking of
flood on the host network.
Tcp min rt timeout
This parameter specifies the TCP/IP reply timeout period. Do not modify and leave this parameter to its
default configuration: 300 milliseconds.
Dsvc max points
The maximum number of points that can be serviced to host applications (excluding NetArrays).
Default value is 20000. This parameter should not be modified.
redundant
Modify this parameter based on the type of system.
For non-redundant systems, this parameter should to be set to 0 (zero).
For redundant systems, this parameter should be set to 1 (one).
BoardID_Chassis0_A, 0_B, 1_A, 1_B, 2_A, 2_B, 3_A, 3_B
BoardID_RedChassis0_A, 0_B, 1_A, 1_B, 2_A, 2_B, 3_A, 3_B
These parameters designate, which processor will be designated as A, B, C or D processor. These
parameters are automatically programmed by the firmware. Modification of these parameters is not
required.
