GX Developer, Parameter values not working

[ianreeves 1]

Hi, has anyone come across the plc parameter values not working. I added an RS232 module to an FX1s unit . Popped the setup values in the communication setting the PLC parameters, but the register isn't populated with the values. Not a huge issue, as just put it in the code. Has always worked on the FX3 series, so I "assumed" the same. Cheers Ian Edited 20 Jun 2014 by ianreeves

Don't know of any differences, but I assume you power cycled the PLC after making parameter changes?

Yes, nothing. The register remains empty. The odd thing is, if I set it up, power cycle the put the correct values in the register ( power cycle ). Then remove the comms setting, I get the message that all values will be set to zero. Power cycle again and they are zero... Must be an issue somewhere, I'll see if my GX Dev is upto date at some point. Have sorted it by putting it in the code, but just wondered. Cheers Ian
