Structure Of The Parameter Data Block For The Fb Im308C - Siemens SIMATIC S5 Manual

Indirect With indirect parameterization (FCT = XX), the FB IM308C takes the
parameterization parameterization data from a parameterization data block and not from the
block parameters.
You must open the parameter data block before calling the FB IM308C.
If the parameter data block is too short, the programmable controller goes to
STOP. All subsequent errors are intercepted by the FB IM308C and output in
the parameter data block.
The parameter data block must be structured as follows:

Block parameters
, The table below shows the meanings of the block parameters which you must
send to the FB IM308C in the STEP 5 application program. You can call the
FB IM308C with direct or indirect parameterization.
