SECTION 1 - INTRODUCTION
OVERVIEW
The Plant Loop to Plant Loop Remote Interface (INPPR01)
enables communication between a local and remote Plant
Loop. Two modes (user-selectable) of control are available. A
local Plant Loop is able to issue control commands and receive
Exception Report (XR) data from up to 32 remote Plant Loops
when it is in the one-way mode. Only the local Plant Loop can
initiate control commands and request exception reports in the
one-way mode. The two-way mode connects only two Plant
Loops. In the two-way mode, either Plant Loop is able to initiate
control commands and request exception reports. Plant Loop
to Plant Loop Remote Interfaces can connect through cable,
modem or microwave link. Figure 1-1 shows a block diagram of
Plant Loop to Plant Loop Remote Interfaces in two-way control.
The INPPR01 is a direct replacement of the Network 90 Plant
Loop to Plant Loop Gateway (NPPG02).
INTENDED USER
System engineers and technicians should read this manual
before installing and operating the INPPR01 module. Refer to
the Table of Contents to find specific information after the
module is operating.

HARDWARE DESCRIPTION

HARDWARE DESCRIPTION
The Plant Loop to Plant Loop Remote Interface acts as another
node on the Plant Loop. The interface consists of three modules
on a dedicated module bus.
Plant Loop to Plant Loop Transfer Module (INPPT01)
This module processes incoming and outgoing Plant Loop mes-
sages, buffers data and communicates with other PPT modules
in remote Plant Loops. The PPT is a double circuit board mod-
ule. It has a memory board and CPU board. The user selects
general operating characteristics and point definitions through
software configuration. Other characteristics such as type of
control (one-way or two-way), Node ID and port options are
user-configured through dipswitches on the CPU board.
Bus Transfer Module (INBTM01)
The BTM is responsible for translating messages from the LIM
and placing them on the module bus. It also receives messages
from the PPT. It translates those messages and sends them to
the LIM through a direct memory access (DMA) cable.
Loop Interface Module (INLIM03)
The LIM provides the communication link between the Plant
Loop and the PPT. It receives messages from Plant Loop nodes
and monitors loop status. The LIM forwards messages from the
loop to the PPT (though the BTM) via a direct memory access
(DMA) cable. Additionally, it receives messages from the PPT
(through the BTM) and sends them to the proper node on the
loop.
Additional Hardware
Some applications require additional hardware such as a
modem network, radio link or microwave link. This hardware is
not part of the INPPR01 standard hardware. INFI 90 Digital
Slave Modules (IMDSO01 through IMDSO04, IMDSM05) sup-
port control signals to these devices.
FEATURES
The Plant Loop to Plant Loop Remote Interface provides com-
munication between a local loop and one or more remote loops.
This interface has user selectable control modes. Selecting the
one-way mode enables a local loop to receive exception reports
from up to 32 remote loops. In the one-way mode, only the
local loop can initiate control commands. The two-way mode
enables bidirectional control and exception reporting between

INTRODUCTION
INSTRUCTION CONTENT
I-E96-624A 1 - 3
a local and one remote loop. This interface handles a maximum
capacity of 5,000 blocks of exception report data.
The INPPR01 can handle a mixture of point types. Point types
include analog and digital station, remote control memory,
manual set constant and device driver. The user can select the
interface communication rate, up to 19.2 kbaud.
INSTRUCTION CONTENT

SECTION 2 - DESCRIPTION AND OPERATION
INTRODUCTION
This section explains the operation of the Plant Loop to Plant
Loop Remote Interface.
LOCAL/REMOTE COMMUNICATIONS
Local and remote PPTs communicate with each other through
a series of commands and replies over the serial ports. In the
one-way mode, the local PPT issues commands only; in
two-way, both the local and remote PPTs issue commands. The
command format is:
where:
1. Loop number is the loop that responds to the command (1
byte field).
2. Message byte count is the total length of the message (2
byte field).
3. Command code is the command code the PPT processes (1
byte field).
4. Command data is the specific command (variable length
field).
5. Checksum is the sum of all the bytes in the command (1
byte field) or CRC, the cyclic redundancy check word computed
for all of the bytes in the command using the CRC-16 algo-
rithm (2 byte field).
All communications between interfaces use this format.
INPPR01 commands are a modified form of Plant Loop to Com-
puter Interface commands (refer to I-E93-905-9 for command
details). The PPT format eliminates the key field from the PCI
command. In addition to PCI commands, the PPT processes a
command (code 29) that permits passage of a required PPT
message.

DESCRIPTION AND OPERATION
DATA INTEGRITY
2 - 2 I-E96-624A
®
DATA INTEGRITY
Verification of data integrity consists of even parity checking
and the checksum in each command and reply format. The
interface retries a transaction whenever it detects a communi-
cation error.
There are two levels of communication breakdown detection.
The first level detects a complete failure of the communication
link. Should this occur, Function Code 130 output block one
will be set (logic one) and the alarm status bit set if port 1 fails.
If port 0 fails, the output of block two will be set (logic one) and
the alarm status bit set.
The second level of communication failure concerns the loss of
a single remote interface. If this occurs, all blocks coming from
that remote interface are bad quality. The PPR makes use of a
user-configurable watchdog timer or absolute retry count in
determining the sensitivity to these failures (refer to
I-E93-200-20 for information about Function Code 130, S10
and S12).
TIMING INTERVAL
The local interface attempts communication twice a second
with all the remote interfaces. Each successful transaction
resets the communication watchdog timer. Therefore, if the
communication link is faulty, no transactions occur success-
fully. After the watchdog time period expires, the link is
marked bad.
For all communication transactions, the watchdog timer is
reset on the reception of each character. If the time interval
between characters in a transaction exceeds 1.25 seconds, the
transaction is flushed and the remote interface is marked as
being suspect. This condition causes retry logic to begin. Retry
logic consists of retrying communication once per second for a
number of times equal to one-fourth the watchdog time period
if the absolute retry count is set to zero. A non-zero absolute
retry count causes a specific number of retries (the number of
the retry count). If the failure persists after the retry period
expires, the remote interface is internally marked off-line and
the quality of all the points it provides are marked bad.
Thereafter, a single retry of the failed remote interface occurs
at a period equal to one half the watchdog timer period until a
successful transaction occurs. The local interface sets the
quality of all the points to their original state (before the com-
munication failure). It also does a one time poll of the current
value of each point.
A user-configurable time delay envelopes each command/reply
sequence. This time delay accommodates the keying up/down

of modems and transmission equipment. The interface coordi-
nates this activity through the RTS (Request-To-Send) signal of
the RS-232-C port for modems or through digital outputs when
using Digital Slave Modules (IMDSM05, IMDSO01/02/03/04)
to enable other transmission equipment.
Transmit/Receive Timing
The user can set up the RS-232-C ports to operate as Data Cir-
cuit-Terminating Equipment (DCE) or Data Terminal Equip-
ment (DTE). In the DCE mode, the Request-To-Send (RTS) line
is always asserted. In the DTE mode, the RTS line is asserted
before data transmission and inhibited after data transmission
occurs.
The following events occur (see Figure 2-1) on port 0 when
transmitting a command:
1. Assert RTS on the RS-232-C port (DTE mode) or set digital
outputs 1 and 4 on the digital slave module.
2. A delay occurs between the time the port 0 asserts the RTS
(or the digital outputs are set) and the command transmission
occurs. Function Code 130 (S5) sets this delay (in
milliseconds).
3. Output 4 is reset.
4. A delay occurs between the time output 4 is reset and out-
put 1 is reset. Function Code 130 (S6) sets the length of this
delay.
5. Output 1 is reset and RS-232-C RTS signal is inhibited
(DTE mode).
6. A delay set by S5 of Function Code 130 occur between the
output 1 reset and the reception of the reply.
7. The remote target issues a reply.
The following events occur (see Figure 2-1) when Port 0
receives a command:
1. The port receives the command.
2. A time delay set by S6 of Function Code 130 occurs.
3. The RS-232-C asserts the RTS signal (DTE mode) or set
outputs 1 and 4 on the digital slave modules.
4. A time delay set by S5 of Function Code 130 occurs.

5. The remote interface transmits a reply to the interface
sending the command.
6. Output 4 is reset.
7. A time delay set by S6 of Function Code 130 occurs.
8. Output 1 resets, RS-232-C RTS signal is inhibited (DTE
mode).
NOTE: RTS assert and inhibit apply to DTE mode only. RTS is
always asserted for DCE mode.
