4-3 Working mode settings
1）Expansion's input/output all have options of voltage 0-5V, 0-10V, current 0-20mA, 4-20mA
modes. Via setting of special FLASH data register FD in PLC. See the following table:

Note: As shown in the preceding table, every register sets the mode of 4 channels, each register
has 16 bits, from low to high, every 4 bits sets 4 channels.
Each channel's working mode is assigned by corresponding register's 4 bits. Each bit's definition
is shown in the following table:
