For parameter E2.15, the relationship between the output of '21:
Parameter setting from communication' and the communication
mode is as follow:
– For modbus mode, when bit8 of register 0x7F08 is '0', Tb_Ta is
opened; when bit8 is '1', Tb_Ta is closed.
– For other fieldbus mode, the output is defined by bit8 of pa-
rameter E2.20.

●
For parameter E2.26, the relationship between the output of '12:
Parameter setting from communication' and the communication
mode is as follow:
– For modbus mode, the output is defined by register 0x7F06.
The value range of register is 0.00 %...100.00 % (It means per-
centage of maximum analog output value).
– For other fieldbus mode, the output is defined by parameter
E2.28.
