jblkiller Posted January 7, 2011 Report Share Posted January 7, 2011 I have a M91-2-R1. I would like to know if I can utilise a RS-485 or RS-232 port to ethernet converter to acces and view online plc? like this on this web site http://www.bb-elec.c...sp?familyid=644 Thanks Quote Link to comment Share on other sites More sharing options...
MVP 2021 Joe Tauser Posted January 9, 2011 MVP 2021 Report Share Posted January 9, 2011 Those devices do work, but you have to install software on any PC that you'll be connecting to the M91 over the network. The software creates a virtual com port on your PC (so you still use U90 in serial mode) and packetizes the commands to that port, sending them on the network to the converter. Joe T.

Ofir Posted January 9, 2011 Report Share Posted January 9, 2011 Hi, You can check the price of V130 with Ethernet port comparing to the M91 with this converter. Please note that using V130 Ethernet port you can open up to 4 sockets and of course this PLC has many other advantages such bigger screen, String library, SD card, Trends, Web Server capabilities and much much more.
