CS8C 98 / 248
Configuration
The
CS8C
parameters of the
PLC
option are:
•
The name of the digital output to be used for the
Overrun
error (
dOverrun
by default).
•
The
TCP
port used for communication with the
PLC
programming environment (
1100
by default).
•
The name of the digital output to be used for the
RwError
error (
dRwError
by default).
•
The percentage of idle time between two
PLC
cycles, when the
PLC
cycle time is null (
50%
by default).
For instance, if the last
PLC
cycle took
16ms
and "idleTime" is
50%
,
8 ms
are left to the system before
a new
PLC
cycle is started.
These parameters are defined in the
/usr/configs/plc.cfx
file, which can be modified by
Ftp

The
ALIAS
field can be used to give a
PLC

this field is empty (
"
:
2
simple quotes) the name of the
PLC
variable is the same as that of the Input/Output.

Automatic creation of the
PLC
