Serial COM2 status
These words define the status of communication
serials COM1, EXP1 and COM2. Each bit of each
word signals a condition of missing communication
(off-line) or an error for each transmitted/received data
by instructions COM_1÷16 or EXP_1÷16 (ex.
SM100.0=1 shows the error on COM_1(...)
instruction).
If serial is selected on slave protocol, the error
condition is signaled setting to "1" all bits of
correspondent word whenever no correct packet with
slave address same as the device is not received
within the time fixed on SM105, SM115 and SM125.
If serial EXP1 is selected as “EXP-I/O-CANBUS”,
each bit of word SM110 corresponds to status of each
expansion module of I/O. Specifically bit 0 defines the
status of module mapped by instruction MapEXP1
(0=module online, 1= module off-line), bit 1 defines
the status of module mapped by instruction MapEXP2
and so on.
