PIO Process image of outputs èprocess image.
Process image The process image is part of a controller's system memory. At the start of the
cyclical program, the signal states of the input modules are transferred to the
process image for the inputs (PII). At the end of the cyclical program, the
process image for the outputs (PIO) is transferred to the output modules as
asignal status.

6 Mounting
6.1 General instructions
CPX terminals are delivered in mounted form. For expansion or conversion, remounting may be
necessary:
– Dismounting or remounting of the connection block when exchanging the connection technology
– Dismounting and remounting of the electronics module by setting the DIL switches or exchanging
the electronics module
Arrangement on terminal CPX
For further information on the arrangement of the modules, observe the description of
system CPX and the module documents èChap. 1.1.
6.2 Mechanically coding the connection block
To prevent an incorrect allocation of the connection block to the electronics module, this connection
can be mechanically coded.
– The electronics module has a permanently
attached coding pin at the top èFig. 4, 1.
– The connection block has a recess for a coding
piece at the bottom.
– Connection block in pre-assembled CPX
terminals are mechanically coded at the
factory. 1
