Hope every one had a good Christmas and isn't working to hard at the moment!!
I got a call from one of my customers and they asked if i would in interested doing the following job..
use a momentum PLC and RS232 to communicate with a Paging system. i said yes but as a learning exercise, so it means i am doing this on mostly my time (Mostly because they are going to pay what they budgeted).
So a couple of questions to start..(I haven't even seen the paging system or know what comms i am able to use..)but before i do here is a simple overview..
existing Modicon Quantum PLC system, 6 different processors covering approx 1500 Digital I/O and approx 100 analog I/O communicating with Modbus Plus also 8 or 9 Cutler hammer panelmates with the same comms. the new momentum processor will be dedicated to the paging system and is also on the modbus plus network. i was informed that they went with the momentum for the XMIT function that this unit has.. The processor will be "looking" at approx 260 points each point will page one of 5 groups and some will page individual pagers.
Now getting the alarms from the other PLC's is no problem for me, the problem is in using the XMIT block,so here goes...
1. am i better to program the processor with Modsoft or concept, If concept what language? Is the xmit function even available outside of 984LL?
2. how do i go about setting up the text to transmit to RS232
3. i can see messages getting bumped so i am thinking i will need some sort of FIFO thing going on and being deleted from the stack as the alarms are acknowledged..
anyone have some suggestions? My day tomorrow is spent in reading the paging manual and some limited info on the xmit..if you know of something else or an example i could expand on it would be much appreciated..
Thanks
