GC-4642 user manual
integer from %Q0.0 address. AT stands for the address of variable access and
the additional attributes of the variable (see page 46 of the e-book for details).
(Note: Input only affects input, output only affects output, output and input do
not affect each other. That is, if there is and only an input module in front of
the output module, then no matter how many input modules are in front, the
address of the first output module is still Q0 .0.)
2.5 Combination with GCAN-IO-8000 series equipment
The status of the analog output is represented by two bytes. For example:
GCAN-IO-8000 module node number is 1, if you want channel 1 of the first
GC-4642 module to output 10mA, and other channels output 0mA, you need to
write CAN data to GCAN-IO-8000 module The frame ID is 0x201, the data
length (DLC) is 8, and the frame data is 0xFF, 0x7F, 0x00, 0x00, 0x00, 0x00,
0x00, 0x00 data.
