The I-7188EF-016 is an uPAC 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.

Advantages of uPAC-based Control System

Compared to PC-based and PAC-based FRnet control system, the uPAC I-7188EF, is much smaller and cheaper. AS a result of the special features of FRnet, such as real I/O synchronization and fixed scan time, the I-7188EF includes PLClike control functions. Because FRnet is so easy to program, users need only take a few minutes to learn FRnet I/O programming.

The I-7188EF has an Ethernet port, meaning that all FRnet products can be controlled via an intranet or Internet. It also has an additional RS-485 port to control our I-7000 data acquisition modules. Using the I-7188EF, thousands of I/O control system channels can be easily implemented. the optional extended flash memory of I-7188EF can record all I/O status events for a greater length of.

The I-7188EF can operate in a wide temperature range and in harsh industrial environment. Compared to PLCs, traditional the I-7188EF has better network capabilities, strong distributed and high-speed deterministic I/O (FR series I/O), cheaper analog I/O modules, cheaper motion control modules, and richer software tools.


FRnet Network
FRnet is an innovative industrial field bus that the many special features, such as
  • High speed deterministic I/O control
  • Real I/O synchronization capability
  • Non-protocol communication
  • Easy used memory-mapping I/O programming
  • One FRnet port to expand distributed I/O module
  • Two wire cabling
Modbus Protocol
  • FRnet I/O mapping to Modbus addresses for Modbus/TCP client access
  • Converts single Modbus/TCP to multi Modbus/RT
I-7188EF-016 acts in a similar and way to the I-7188E-MTCP Modbus/TCP gateway. It can easily upgrade many Modbus/RTU devices connected to the COM ports of I-7188EF-016 to give Ethernet communication abilities.
ASCII-based Protocol (DCON Protocol)
I-7188EF-016 includes the DCON protocol, which is a request/reply communication protocol that is used to access the data from the module using a simple ASCII format. For example, sending the command "$ 01M " will query the controller name. The responding module will reply with a message similar to "!017188EF-016(cr)".
Various DCON SDK Provided (Free)
In order to access the FRnet I/O of the I-7188EF-016 from the host and the remote I/O modules connected to the I-7188EF-016. Various SDKs have been provided on the CD, such as:
  • DLL driver
  • ActiveX component
  • LabView bundled driver
  • Indusoft bundled driver
  • Linux driver
  • OPC server
Firmware Modifiable
The Modbus and the other related SDK is provided for users to develop their own custom firmware.
Built-in Watchdog
The built-in watchdog circuit will reset the CPU module if a failure occurs in either the hardware or the software. If the application program does not refresh the watchdog timer within 0.8 sec, the watchdog circuit will initiate a reset of the CPU.
