Hello Cy, If you need to change DM value temporally (untill PLC restart) you can send "WR DMxx yyyy "command via RS-232 , like "WR dm10, 100". If you need to change DM value permanently you should modify a program inside the PLC . There are few ways to do it without the Ladder Builder: 1. You can use our "PLC Easy DM Editor" software utility. At the moment it is in state of Beta version. We expect to have the release version v.1.0 in September 2005. If you would like to have the beta version, please send your email to support at plcutils.com 2. If you want to do it from your software you can use our SDK to read program from PLC, modify DM or Timer values and program it back into the PLC. See: SDK for Keyence PLC For both options you don't need to have a source code of PLC program. Edited by plcutils
