OPTOMUX - IOPLEXER

FORMATS FOR I,O AND Y CLUSTERS

FIRST, QTY, BOARD, POS, ALA, ENABLE

CLUSTER FORMAT FOR A

FIRST, QTY, BOARD, POS, ALA, ENABLE, PROBE

FIRST the index of the first RTES variable in the cluster

I clusters read binary channels into I registers
O clusters write O registers to binary channels
A clusters read analog channels into A or R registers (depending on the PROBE
parameter)
Y clusters write Y registers (raw values) into analog output channels.

QTY the number of variables in the cluster

BOARD the address of the OPTOMUX board (decimal)

POS the position of the first channel to be transferred

ALA the index of the RTES alert register

ENABLE the index of the RTES enable register

PROBE analog inputs only:
If 0, request the counts from the OPTOMUX board and use them as raw
values for the 'A' variables.
If >0, request the EXTENDED TEMPERATURE READINGS for the
probe type corresponding to the value of PROBE and place them in the
'R' registers.
The value of PROBE must match the analog input module type you use:

1 ICDT
2 10 OHM RTD
3 100 OHM RTD
4 TYPE J THERMOCOUPLE
5 TYPE K THERMOCOUPLE
6 TYPE R THERMOCOUPLE
7 TYPE S THERMOCOUPLE
8 TYPE T THERMOCOUPLE
9 TYPE E THERMOCOUPLE

COUNTERS

Each counter is defined by a G cluster. You may define up to 64 counters.

The format of a counter cluster is :

register: the index of a RTES register where the count will appear. The next 2 registers
are used to control the counter:

set the first register to true to count.
set the second register to true to clear the count. (it returns to false
when count is cleared)

0: a dummy argument to maintain the cluster format.

address: hardware address of the OPTOMUX board where the counter is.

position: position (0-15) of the counting input on the board.

alarm: index of the register that will indicate a non or bad response from the counter.

enable: index of the register that controls the communication with this counter. If the
register is on (1 or odd value), RTES will attempt communication with this
counter, the counter will be ignored otherwise. Any register, starting at R0002
may be used. If you use 0, a enable register does not apply: RTES
communicates with the counter continuously. This register is not affected by the
C option, the enable register is never returned to 0 automatically.

Example:

We want to count the false to true transitions of the input located at position 5
of board address 200. The count will be read into register R0150. R0151 will
be used to start/stop the counter, R0152 will be used to clear the counter.
Communication alarm will be annunciated at register R0005. There is no enable
register.

The configuration file will include:

G=1 149,0,200,5,4,0

PULSE DURATION MEASUREMENT

A digital input may be used to measure a pulse duration.
Each pulse duration to be measured is defined as a "S" cluster.

S=n n-number of pulse measurements defined

each pulse measurement cluster consists of the following parameters:

register index of the RTES register that RETURNS THE LATEST PULSE DURATION
in increments of 10ms
register+1 PULSE STATUS - a 1 indicates that pulse is completed
register+2 CLEAR COMANND - set this register to 1 to reset the two registers above
address BOARD ADDRESS
position OUTPUT POSITION
alarm COMM. FAIL REG
enable RUN SWITCH - Turn this register to 1 TO MEASURE A PULSE

Example:
We want the 2nd output (position 1) on board address 253 (FDhex) to measure a pulse when
R0053 is set to 1.

We will use R0001 as communication failed indicator and R0050-R0052 to operate the process.

The configuration file will contain:

S=1
49,0,253,2,0,52

RTES registers will be set as follows:

R0001 A253 0.00 1 Board 253 (FD) not responding
.
.
R0050 DURATION 40.00 Pulse duration in increments of 10ms
R0051 STATUS 1.00 Pulse complete when on
R0052 CLEAR 0.00 Turn on to clear the measurement
R0053 SEND 0.00 Set this to 1 to read the pulse(s)

PULSE STREAM GENERATOR

A digital output may be used a pulse generator.
Each pulse generator is defined as a "p" cluster (lower case p).

p=n n=number of pulse generators defined

Each pulse generator cluster is defined by :

register PERIOD IN MULTIPLE OF 10mS
register+1 NUMBER OF PULSES
address BOARD ADDRESS
position OUTPUT POSITION
alarm COMM. FAIL REG
enable TRIGGER - RETURNS TO 0 WHEN DONE

Example:
We want the 3rd output (position 2) on board address 253 (FDhex) to send a 200ms pulse when
R0053 is set to 1.

We will use R0001 as communication failed indicator and R0050+R0051 to define the pulse.

The configuration file will contain:

p=1
49,0,253,2,0,52

RTES registers will be set as follows:

R0001 A253 0.00 1 Board 253 (FD) not responding
.
.
R0050 PULSE 40.00 Pulse period (200ms on/200ms off)
R0051 NBR 1.00 Number of pulses
R0052
R0053 SEND 0.00 Set this to 1 to send the pulse(s)

OPTOMUX over IP
You must install the TCP/IP stack (EXNET)
Use TOPTOMUX for TCP/IP
Use UOPTOMUX for UDP

Add to the configuration file:

P=n	(n=qty of OPTOMUX modules used)
For each module add a line consisting of 5 numbers:
optomux address, 1st IP byte, 2nd IP byte, 3rd IP byte, 4th IP byte

For example:
;Configuration file to read 16 digital inputs from OPTOMUX address 22 at IP 192.168.0.22:
P=1
22,192,168,0,22
I=1
0,16,22,0,0,0
