You can write IMC II equipment's setting value by using write settings.
Note) Write for IMC II can control when the equipment's setting is 'remote'.
Digital Write
Digital write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION IMC II controller station number = 0 ~ 255.
3) ADDRESS Setting data type.
0000 – Forward ON/Stop operation,
0001 – Reverse ON/Stop operation,
0002 – Reset.
4) Extra1 Model name = IMC2. ( IMC II model )
5) Extra2 Don't care.
Write example 1)
PORT : 0 Station : 1, ADDRESS : 0000, EXTRA1 : IMC2, EXTRA2 : 0
The setting parameter shown above is Forward ON/Stop operation control example for 1 controller station IMC II.
Forward ON/Stop operation write command can control when the controller's setting is 'remote'.
Write example 2)
PORT : 0 Station : 1, ADDRESS : 0001, EXTRA1 : IMC2, EXTRA2 : 0
The setting parameter shown above is Reverse ON/Stop operation control example for 1 controller station IMC II.
Reverse ON/Stop operation write command can control when the controller's setting is 'remote'.
Write example 3)
PORT : 0 Station : 1, ADDRESS : 0002, EXTRA1 : IMC2, EXTRA2 : 0
The setting parameter shown above is Reset control example for 1 controller station IMC II.
Reset write command can control when the controller's setting is 'remote'.
Digital Write
Digital write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION IMC II controller station number = 0 ~ 255.
3) ADDRESS Setting data type.
0000 ~ 0010 – setting 1 ~ 2 (Extra2 = 0 ~ 1 ) writing address. refer to <Table 9> ~ <Table 10>,
0000 ~ 0002 – setting 3 writing address. refer to <Table 11>.
4) Extra1 Model name = IMC2. ( IMC II model )
5) Extra2 Selection of setting 1 ~ 3.
0 – setting value 1,
1 – setting value 2,
2 – setting value 3.
