Hardware Configuration I/O Expansion Modules
VisiLogic: Getting Started 39
The formula that is used to calculate the number of the I/O is:
32 + x • 16 + y,
where X is the number representing the location of the module’s location (0-7)
and Y is the number of the input or output on that specific module (0-15).
Examples
Input #3, located on module #2, will be addressed as I 67
67 = 32 + 2 • 16 + 3
Output #4, located on module #3, will be addressed as O 84
84 = 32 + 3 • 16 + 4.
Remote I/Os
The EX-RC1 enables you to distribute I/O Expansion Modules throughout your
system. The adapter is connected to a master PLC by UniCAN, Unitronics’
proprietary CANbus protocol, and functions as a slave device within that
network. Each adapter may be connected to up to 8 I/O expansion modules.
The network may include up to 60 devices.
The EX-RC1 is run by a factory-installed VisiLogic application. You can upload
this application and tweak it to adapt it to your system.
Note that the adaptor has the ability to auto-detect digital I/O Expansion
modules that are connected via CANbus. This means that if your system
includes only digital I/O Expansion Modules, you do not have to define the
Hardware Configuration.
