It depends on which PLC you are using. If it was a SLC500 I would add a basic module which makes ASCII handing operations very easy. Regards Mike

Check out the following :-http://literature.rockwellautomation.com/idc/groups/literature/documents/in/1771-in024_-en-p.pdf. The output module has minimum load requirements with capacitor and snibber resistors across the output. Regards Mike

Use not dn of timer 2 to drive input of timer 1. Use dn of timer 1 to drive input of timer 2. Use not dn of timer 1 to extend cylinder and dn of timer 1 to retact cylinder.

Allen Bradley documentation gives the backup times for the SLC5/04 as two years. Don't know about hte PLC5 though. Regards MSW

If you are setting RSlinx to use the 1747-PIC driver then under Channel configuration on the SLC5/05 the channel 0 - system setting must be set to DH485, baud rate will automatically be set to 19200 and set the appropriate node address. Under General the Channel 0 mode must be set to System...

I don't have your code but I use calls 3 and 2 to transfer data, remembering to set Block lengths first. The PLC5 programe should have a one shot on the leading edge of the BTW check pending (bit I:xx/1)and in the BTW enable logic use this OSR with your signal that data is required to be sent to...
