Configuring PID Address
Calculating the PID address
| PID address | Formula | Note |
| Address for PID argument | A=(2048+S*256)+16*C | S is the installing slot no.of the module (0~6) C is the point no.( 0~7 for 8PID module and 0~3 for 4PID module |
| Address for PID positive pulse | X=(2048+S*256)+12 | |
| Address for PID negative pulse | Y=(2048+S*256)+13 |
