PCCC
PLC5 and SLC500 PLCs use PCCC messaging. The IDENTControl Compact supports PCCC.
The data telegrams receive the output and input data from the selected assembly object.
Observe the sequence of the bytes (see example).
Supported PCCC commands:
■
Write PLC5 type point-to-point
■
Read PLC5 type point-to-point
The data is written as an integer data set starting with N14:0. The data is read as an integer
data set starting with N7:0. The assembly instance determines the length of the data.
Example: Assembly instance 104, single read command
Configure output instance 104d in the
Network
window on the IDENTControl Compact
website.
