The I-7188EF-016 is an μPAC with isolated FRnet, Ethernet, RS-485 and RS-232
ports. I-7188EF-016 is designed to make that the Host PC easily access the FRnet
I/O module via Ethernet. I-7188EF-016 controls the distributed FR-2000 and FR I/O
module via FRnet, and provides the Modbus and DCON protocol for HOST PC to access
these FR I/O channels via Ethernet.
The I-7188EF controls distributed FR-2000 and FR I/O modules via FRnet. Each I-
7188EF can control a maximum of with 16 groups, each group having a maximum of 16
I/O channels. In other words, each I- 7188EF-016 can control a maximum of 128 digital
input channels and 128 digital output.
MiniOS7 is pre-installed on I-7188EFand is ready to run your C software programs.
In addition to being used as a converter, I-7188EF-016 series can also be programmed
as an autonomous controller to control distributed FR-2000 I/O modules via FRnet.
