I’m new to B&R systems. I’m trying to modify some acoposmulti parameters, but without success. Can someone help me with how to read and write acoposmulti parameters via logic? I’m using MappMotion.

Hello,

You can use [MC\_BR\_ProcessParID\_AcpAx](https://help.br-automation.com/#/en/4/motion%2Fmapp_motion%2Fprogrammierung%2Fbibliotheken%2Fcore%2Fmcacpax%2Ffunktionsbausteine%2Fmc_br_processparid_acpax%2Ffb_procparid.html) or [MC\_BR\_CyclicProcessParID\_AcpAx](https://help.br-automation.com/#/en/4/motion%2Fmapp_motion%2Fprogrammierung%2Fbibliotheken%2Fcore%2Fmcacpax%2Ffunktionsbausteine%2Fmc_br_cyclicprocessparid_acpax%2Ffb_cprocparid.html) (if you need cyclic operation).
