Operating Conditions and Format Set Content

The programmable controller can change from using no protocol communication to programming

protocol (and back) by manipulating the RS instruction and Register D8120 and shown below.

1 ) With the RS instruction ON, move the data options shown below into the Register D8120 to

use no protocol communication.

2 ) To use programming protocol, turn the RS instruction OFF and move the data H0000 into the

communication format Register D8120. When the programmable controller is taken out of

RUN mode (by FX-PCS/WIN-E Software or the front panel switch), complete editing and

program downloads can be accomplished. On line changes can be performed with the

programmable controller in Run Mode.

Example of changing the communication format (D8120) between H0086 and H0000. The

programmable controller is first set for no protocol communication using the RS instruction.
