6.3 Digital Input/Output Channel of Z-DIO Module
Setting the Z-DIO module address determines the digital input/output channel number of SRZ unit. To
each Z-DIO module address, the relevant digital input/output channel is assigned. Each digital
input/output channel can be calculated from the following equation.
Digital input/output channel number
[Module address setting
a
]
[Maximum channel number of the function module
b
]
+ [Input (or output) channel number in a module]
a
When the setting is A to F, it is a decimal number.
b
For the Z-DIO module, it is calculated by “8.”
Example: When 16 Z-DIO modules are joined
