5.3.2 RS485/Mbus Output for Modbus RTU

*For A-400MT/-M

For Modbus RTU, the following RS485 communication parameters can be conﬁgured from the

set-up menu:

Baud rate 2400, 4800, 9600, 19200, 38400

Parity none / odd / even

Stop bits 1 or 2

RS485 network address nnn - 3-digit number, 001 to 247

*For A-400MB only

For Mbus, the following communication parameters

can be conﬁgured from the set-up menu:

Baud rate 300,600,2400, 4800, 9600

Parity none/ odd / even

Stop bits 1 or 2

Mbus network primary address nnn - 3-digit number,001 to 250 Mbus network secondary

address 00 00 00 00 to 99 99 99 99

5.5 Reference Conditions of Inﬂuence Quantities

Inﬂuence Quantities are variables that aﬀect measurement errors to a minor degree. Accuracy

is veriﬁed under nominal value (within the speciﬁed tolerance) of these conditions.
