Posted 8 Sep 2004 I need to make modem connection between my pc and two Q00CPU. I have one Westermo TD33 analog modem on remote side. My idea is to use two QJ71C24N serial cards installed on the two plc rack and connect TD33 modem to 232 port of first C24N card. Then connect the 485 ports of both C24N, so to realize a drop connection and chose plc number with GX Developer during modem connection. What do you think ? anybody have expereance or suggestions? best regards Max :-8 Share this post Link to post Share on other sites
Posted 8 Sep 2004 There is no problem doing it this way though you would be better connecting you westermo dirctley to the programming port which would save you the cost of a c24 card ???. My company provides configuration software for the westermo modems and ready made cables for all mitsubishi to westermo program and transfer routes as starter kits.
