SM97 2097
Answer delay/Waiting data on receipt COM2 (default 0 ms)
The value of this word defines:
•
Slave protocol: minimum delay between end of
serial receipt from a master device and the start of
answer broadcast from PLC (max 100ms).
•
Master protocol: max. waiting between start of
polling broadcast from PLC and complete receipt
of answer from slave device.
•
Value is expressed as ms.
R/W
SM90 2090 Number of errors for signal about status of COM1 (default 10)
SM98
2098 Number of errors for signal about status of COM2 (default 10)
Value entered for this word defines the number of
consecutive communication errors after which the
anomaly is notified in the relevant bit of “serial status”. R/W
SM94 2094
Number of characters RX on IR (default 8)
Number of characters for each data package received
on IR port.

1.7.3 Memory area “digital inputs I”
This memory area “digital inputs I” is the area in which the state of digital
inputs is stored. It is organized in words; each of the 16 bit of the word
represents the state of an input. For instance: the state of digital input I20 is
stored on bit no. 3 of word 2 in area I. The area consists of 4 words. The
first and the second are updated with actual state of inputs at the starting of
each cycle, while the last two words may contain the state of inputs read
via serial communication from an expansion module.
1.7.4 Memory area “digital outputs Q”
This memory area stores the state of digital outputs. It is organized in
words; each of the 16 bit of the word represents the state of an output. . For
instance: the state of digital output Q1 is stored on bit no. 0 of word 1 in the
area Q. The area consists of 8 words. The first one is transferred to the
outputs of PLC at the end of each cycle, the other ones may contain the
state of further outputs to write them via serial communication on an
expanded module.
1.7.5 Memory area “support marker M”
The memory area M contains teh status of all markers (bit contacts) used in
the program. It is organized in word; each of 16 bit of the word means the
