Hi there,
I am a new learner in PLC programming and I need help in making the following works.
What I need to do is to read a 3 digit decimal number, say '123' (a 16 bits word) from a touch panel into an address inside an Allen Bradley PLC processor (say N7:10).
According to the user manual of the touch panel, a trigger bit/address has to be given to the touch panel by the PLC processor and then the value entered through the keypad on the touch panel will be read into the given address at the PLC processor. The example given by the manual is 'M0080' but obviously, it is not a valid address for Allen Bradley's PLC processor.
I read through the PLC processor manual but it has not got information about the trigger bit. Just wondering is there anybody can help me out.
Many thanks!
Norris
