COMPARE INSTRUCTION -CPM1A

[kuttiess 0]

Hi to all, Is it to possible to compare a string, which is in DM100 TO DM109 with the strings which are in DM300 TO DM309, DM310 TO DM319. From the instruction help i come to know CMPL compare only 2words at a time. If any other possibilities please guide me. PLC : CPM1A CPU20 SOFTWARE: CX PROGRAMER

The CPM1A has a fairly limited set of instructions so you are probably not going to find anything that works better than the CMPL instruction.

Hi to all, Finally i used couple of CMPL instructions to compare the strings whether they are equal or not. Meanwhile i faced a problem,while programming my HMI related to this project. Atlast,today i complete everything. Thanks to all, specially Mr.Dick Oestreich for his advice.
