EX-RC1 is a remote I/O module that communicates between Vision PLC`s through UniCan protocol. UniCan is a propetary protocol of Unitronics that runs under CANBus. To transfer data to/from the PLC and the EX-RC1 you need to write a small logic to send the data with a vector. Attached an example for the PLC and EX-RC1.

Dear Lawry, I have created a new project in VisiLogic V9.7.60 (last version, OS 4.0(32), Boot 2.2(23)) and filled approximately 700 operands with data, then update my VisiLogic version to V9.8 (official version, OS 4.2(10), Boot 2.2(23)), after a night without power to the PLC, all my operands were still stored. Version update should not cause operands to be erased. Was this behavior limited only to this project? From which version did you updated from? Can you please check SB8 (Battery Low 1=Low)?

Hi Mizinia, High speed interrupt can be use only with snap-in HSI or on board HSI, it can’t work with local expansion IO. V130-33-B1 has no on- board IO and high speed interrupt cannot work with Ex-D16A3-TO16 expansion IO module. There are two options: Using V130 with onboard high speed inputs. Or if you need to high speed input far from PLC then you can use the EXF-RC15 (High Speed remote IO) via CANbus communication. This Remote IO support: 9 digital inputs, including 3 high-speed counters. 4 digital transistor outputs, may function as high-speed PWM/PTO outputs. 2 relay outputs. http://www.unitronics.com/Downloads/Support/IO%20and%20COM%20Modules/IO%20Expansions/EXF-RC15_.pdf For more information on Interrupt you can check VisiLogic Help under "Interrupt Routines"
