MODBUS PLUS CAPABILITY

CHAPTER 9: PROGRAMMING GROUP 0 - GLOBAL METER SETUP

9.4Modbus Plus Capability

When using the MPI Modbus Plus adapter, the meter values should be set to speak to Modbus RTU with a meter address of 0001 and a baud rate of 9600 baud. The Modbus Plus address is programmed into the MP1 Modbus Plus adapter directly.

9.4.1Printing Option

To print, access Mode 1 and Mode 2 (see Part I: Installation and Operation). Printing serial options should be disabled when using a multimeter communications connection RS485.

DISABLING PREVENTS:

1.Printing through the keypad.

2.Corrupting data at a computer terminal while multiple meters poll.

3.Corrupting printing commands through communications.

This option connects a serial printer to the RS232 port and prints the data. Disable this feature when the meter is not using an RS232 port (i.e., when RS485 or DC outputs are being used).
