Hey everybody,
I have two Micrologix 1100 connected via a serial cable between the two 9pin rs232 ports. I am trying to send a simple ASCII message from one ML1100 to the other and then to display it to the screen. I changed the channel 0 to an ASCII channel on both units and I am sending a 9 character message "SYSTEM ON" once ever second through the serial cable. I verified i am transmitting using hyper terminal. I can't seem to get the message to read. on the other ML1100. Anybody have any ideas. I would like to have the two controllers send several strings to each other and have one simply display the incoming messages on its LCD, maybe fire and output off the DN bit of the read function. Anybody have any ideas. Thanks in advance. The instructions i am looking at are ARD (ASCII Read) and AWT (ASCII Write). Any help would be appreciated, or if somebody has a better way using other commands i would be open to using that as well. Is it possible i need a null modem converter?
Thanks,
George
