When adding a new modbus operation, i.e., a "Registers Periodic", at the end of the row, there is a "Status" to be add for monitoring individual operation. When link a tag to the status filed to contain the Modbus transaction status, I can get a "-2" to show on my HMI screen. When I look at the Help page, the table for status codes is not shown correctly. Would you please help to show the complete content of this table. Thanks!
