YPLS,ZPLS implemented Later 1.14_04 comaptible with the same commands of MPC-816
MPG-2541is not recommended. discontinued
Why do you waste your time to program PLCs ?PLC 'language' is too primitive to program for modern machineries.

MPC language is BASIC like and supports Multi task Programming. This means MPC realizes Data connectivity , Programmable numerical Control and Flexible programming.
And we have succeeded to add a new IOT MPC named as MPC-3000. It has TCP/IP communication function and many TCP/IP protocols like MODBUS-TCP.
