LCD2041 on AB PLC5
Posted: Thu Dec 18, 2003 8:17 am
I connected a LCD2041 to an AB PLC5 and it works great. I didnt change any of the default communication settings on Channel 0 except the baud rate(I used a PLC5/11 and there is only one serial port ch 0)
My settings were:
baud rate: 19.2k
communication mode: system (point-to-point)
bits per char: 8
stop bits: 1
no handshaking
no parity
bcc error detect
I did have to change the settings on the ascii options (channel configuration then select ascii(user as the communication mode))
I changed the termination characters to:
termination character 1: \0x0d 2:\0xff
append character 1:0x0d 2:0xff
change the communication mode back to system and then select ok.
attached is the sample program I used and the message strings I used. It was real easy to setup. If you cannot get the files please email me.
