Hi All
I have been working on a project which involved modifying an EasyBuilder (MT8000) project used to log data from several SLC5/05 64K PLCs connected via Ethernet in the same panel through 1 switch.
My project involves the logger grabbing data from two of the PLCs at On<>OFF transition every second. Then logging it at 2 second intervals. When I download the Logs the Data is repeated for at least 2 consecutive records giving me a minimum definition of 4s. This is not as fine as I would like and surprised me. I have made several changes to the program to get it that fast it originally was minimum 6s.
Am I expecting too much of the system.
Thanks
Ian
Here is some info about how the system is set up.
The PLCs are set to service comms immediately (S:2/15=0)
A macro grabs the data from various PLC data regs and writes it to consecutive local data words in the data logger. The macro is triggered by LW_Bit-0901701 transition ON<>OFF.
The Data log object records the data from the local memory every 2 seconds.
