I have a setup of IM 151-8 PN/DP F-CPU and a 4SI Elektronik Module IO-Link. I have configured the hardware and the IO-Link device with S7-PCT. Now my task is to read the parameters of the IO-link device using FB "IOL_CALL". I installed the blocks but I am not sure whether I am approaching the steps in the right way. So I tried relating a data block with the FB and check for the parameters. Could anyone help me with the steps to approach this problem?
