Introduction
This IPI describes the Ethernet Option module for a VersaMax Micro-20, -40 or -64 PLC CPU. This module
cannot be used with other types of VersaMax Nano or Micro PLCs.
For more information about Option Modules, and about VersaMax Micro-20, -40 and -64 PLCs, please refer
to the VersaMax Nano and Micro PLCs User’s Manual, GFK-1645J or later.
Important Product Information
Functional Compatibility
The default data rate with Ethernet option module firmware version 2.0 is 175000 bps. Micro firmware
versions below 3.83 do not support 175000 bps. If firmware version 2.0 is to be used with Micro firmware
versions prior to 3.83, the data rate on Ethernet Option module should be changed to 38400 bps or less, as
per the requirement.

RJ 45, 10/100 Mbit Ethernet Option module supporting SRTP.
Upgrades
All previous versions can be upgraded to this firmware version. Once the module is upgraded to the 3.3
version, it will not support downgrade to older revision. Attempting to downgrade firmware may cause the
module to fail permanently.
Note: To reduce the risk of this being accidentally or maliciously used, to permanently disable the module,
Emerson strongly recommends that TFTP be disabled by the user, and only enabled via (password-
protected) telnet when a firmware update is required.

Configuration
Use of the Port Option module as Port 2 and the protocol selection must be set up in the configuration
software. After making those selections, the communications parameters can also be configured.
The option port should be configured for Ethernet. If the configuration and hardware do not match, the
PLC logs a System Configuration Mismatch fault in the PLC Fault Table.

Setting the IP Address
Key items to remember when setting the IP address on the VersaMax Micro Ethernet module (IC200UEM001):
•The default IP address is 10.10.0.5.
•IP address setting must be saved to the Flash on the Ethernet module or it will be lost during power
cycle.
•The second port of the Micro PLC must be configured for Ethernet.
Setting the Permanent IP Address
1. Go to C:/ Prompt on your computer and type: Ping [IP address] and press the Enter key. (This step
is required to “establish” the ARP table by creating an entry in the table.) The address pinged should
reply with Pinged data. (example c:/ Ping 10.10.0.5 and return data)
2. Type: arp –a(space between p and –a). You should see at least one entry in the ARP table. (example
c:/ arp –a)
3. Type: arp –s [IP address, including dots] [MAC Address of the Ethernet module, including dashes]. You
will not see any reply on the screen. (example c:/ arp –s 10.10.0.5 00-20-4a-ff-ff-e9)
4. Type: telnet [IP address] 1 (leave space between IP address and 1) and press the Enter key. You will
be prompted that the connection failed. This is normal. (example c:/ telnet 10.10.0.5 1)
5. Type: telnet [IP address] 9999 (leave space between IP address and 9999) and press the Enter key.
You will be prompted to Press Enter to go into Setup Mode. You have two seconds to press the
Enter key again. If you get the message “Connection to host lost”, re-enter telnet [IP address] and
press the Enter key twice to get to the setup screen. (example c:/ telnet 10.10.0.5 9999)
6. Press 1 to change IP address (Enter the desired IP address) and Net Mask
7. Press 2 to change Serial Settings. For best performance, set the baud rate to 175000. Setting should
be Mode#1, RS232 175000, 8, 0, 1. Port 2 needs to be configured with PAC Machine Edition to
match these settings. Machine Edition should configure Port 2 for Ethernet and baud rate of
175000.
When complete, press Sto save to the Ethernet module. You will see a prompt that informs you Parameters
saved, Display will Restart…. and then Connection to host lost. The data is now stored in the internal Flash
of the IC200UEM001. You can change the settings by repeating the above steps.
Settings are now complete. Verify that Port 2 matches above configuration by connecting to the Micro PLC
serial port and checking hardware configuration.

Downloading is done using the PumpKIN utility, which is included. To download a driver, perform the
following procedure. Only one driver can be present at one time. After the driver has been downloaded you
will have to reconfigure the port using Telnet.
To Download Ethernet Drivers:
1. Before performing the firmware upgrade, make sure TFTP Download is set to Enabled.
Note: Refer to the Security Settings section for more details.
Important: Failure to enable TFTP Download before updating firmware can result in damage to device.

Telnet Configuration
The Ethernet option module will be power cycled and reset under the following conditions:
•A connection to the Ethernet option module is established through TELNET and disconnected
immediately.
•A connection to the Ethernet option module is established through TELNET, the configuration is edited,
and you press "Q" (Quit without Save).
Serial I/O Configurable Parameters
Baud Rate
The supported baud rates are 19200, 38400 and 175000. This baud rate should match the baud rate of the
configuration software.
I/F Mode (Interface Mode)
The Interface (I/F) Mode is a bit-coded byte entered in hexadecimal notation.
The following table displays available I/F Mode options:
Note: All bit positions in the table that are blank represent “don’t care” bits for that particular option, which
can be set to either a 0 or 1 value. Only RS-232C is supported and hence Bit 0 and Bit 1 always should be
zeros. If you attempt to select an I/F Mode bit that pertains to RS-422/485 settings, the WARNING: RS-422/485

Security Settings
Note: This information replaces the “Security Settings for the Ethernet Option Module” section in chapter
14 of GFK-1645J and will be included in the next revision of that manual.
Security settings are provided to prevent unauthorized access to the Ethernet Option Module configuration
mode.
Five security parameters are supported for the Ethernet Option Module (firmware versions 3.3 and later).
Security settings are provided for the three protocols: SNP/SRTP, Modbus TCP and Tunneling.
These parameters allow you to configure the Telnet password, enable the required ports and disable the
unused ports
Figure 19: Security Settings
Note: We strongly recommend configuration of the Telnet password and closing the unused ports. This will
reduce the exposure to security threats.
These ports are disabled by default. A port must be enabled if the application needs a service associated with
that port.
To upgrade firmware, the TFTP Download must be enabled. Be sure to disable TFTP Download after the
firmware update has been completed.
To connect with Device Installer, Port 77FE must be enabled.
For use as web server the configuration for Web Server must be enabled.
By default, Simple Network Management Protocol (SNMP) is Disabled.
For Modbus TCP and SRTP protocols, these security settings options are in the "Network/IP Settings" menu.
For Tunneling (Passthrough), these security settings are in "basic parameters/server" menu.
The maximum password length is 16 characters. These characters can be alphanumeric or special characters.
The password requires a minimum length of 8 characters.
A password set on a protocol’s firmware remains in effect if the firmware is changed to that of a different
protocol. For example, if a password is set on Modbus TCP firmware and later the firmware is changed to
SNP/SRTP, the same password set on Modbus TCP firmware will still apply.
