Hi to all
Im having a problem with a control system we built for a bitumen sprayer. The trouble is that the system will freeze occasionally for about 0.5 to 1 second causing chaos on the spray run. The system uses two T100MDs connected in master/slave configuration via the RS485 connection. Both PLCs are fitted with MX-RTC battery/data modules. The Slave unit monitors bitumen pump speed and switches 10 selectable spray nozzles. Master unit monitors ground speed, touch screen, and control switches, it also controls bitumen pump speed. It appears that some conflict is taking up all the master units time, when the fault occurs the numbers on the touch screen also freeze. Both PLCs have been replaced, but fault still happens. Could the MX-RTC module possibly cause this by being faulty or data storage full ?
Thanks for your time
