Carlos, You probably want to get a hold of the CS/CJ/CP Communications Commands Reference Manual from Omron. W342-E1-12 The memory area code of 31 is for the Work Area (WR), addressed by bit. (Section 5-2-2 page 165) Some common memory area codes are: 30 - CIO by bit 31 - WR by bit B0 - CIO by word 82 - DM by word The command breakdown for Memory Area Write is on page 174. (Section 5-3-3) 0102 - Memory Area Write 31 - Work Area, by Bit 0000 01 - W000 bit 1 (first 4 bytes are word address in hex, next two are bit in word) 0001 - One item to write 01 - Data for item Hope this helps out. Steve

Thanks Jay. I had looked in the PLC Settings but not the PLC properties. I also had missed the section in the manual about the refresh mode. I don't have time now to change all of the timers over to binary, but this will help us in the future. Thanks again, Steve

I am working on converting our equipment from CQM1H to CJ1 and there is one area I can take advantage of the longer timing of TIMX versus TIM. However when I use the TIMX instruction and then compile I get the following error message: ERROR: Instruction TIMX(550) is not available - The timer/counter execution mode is incorrect at rung 38 ( 6, 0 ). I am not sure if this is a software setting in CX because in addition to changing PLCs we also switched from SYSWIN to CX. Or it could be an incompatibility with the CJ1M-CPU12 we are using. All of the documentation I found says the timer will work but I get this message anyway. I tried setting up a test project for a CS1 to see if the TIMX instruction was only available there but I got the same error. I am using CX-Programmer v4.03 Any insight you can contribute is appreciated. Thanks, Steve
