I have an application that currently is running on a CompactLogix L35E with a devicenet network. Off the devicenet, I have some Vorne Digital Displays that are driven serially. In order to make these work, I have used a ANYBUS communicator to convert the data from a devicenet connection to serial. The problem that I have with it is I have to do some funky conversion of data in and out of ASCII formats and the 16 virtual displays that I have have slower than desired update times.
I am thinking of converting this system to an EthernetIP connection so I can send ASCII data out directly from the PLC instead of the current conversion process I use. My thoughts are that by using the E-net connection I can speed up the update rate by sending one longer string of ASCII data to all the displays at one time and let the displays use the data they need.
With transitioning to E-net communications, I can't directly understand if I can communicate to this module without having to purchase the RSNetWorks for Enet. I was hoping that since this is actually done by one ASCII string of 100 characters or so to ones serial input of the displays, that I could write a message instruction to take the ASCII data out the Enet connection and have it arrive at the Lantronix UDS 1100 every 3 seconds or so.
Does anyone know if I can send out a simple ASCII string via this compact logix E-net prot with just properly configuring a message instruction (without the purchase of additional software)? And, if this can be done, can someone help me get started on the proper configuration for this message statement? Note the communications only needs to be done one way (just simply out the E-net port to the Lantronix box with out any type of special handshaking configuration... just a simple ASCII string of +/- 100 characters or so).
Any help, guideance or suggestions would greatly be appreciated.
Thanks, Brett
