Hi, i’m working on a project where I have to read some data from a power meter using Modbus TCP, write the data to MySQL database and generate periodic reports. The plant already has its control system with Ignition 7.2.11 and Kepserver for OPC communication. My question is what would be more recommended, if using Modbus TCP driver from Kerserver or from Ignition. For the start it is going to be just 1 meter but if everything goes well more meters will be integrated to the system. Thanks.

If you’ll be polling the meters at a relatively slow rate (10s or slower) then Kepserver’s Modbus driver is probably a better choice. Otherwise it doesn’t matter.
Well, not counting all the bugs fixed since that ancient version of Ignition was published....
