    Item Not Available  


The uPAC-5207 has officially been phased out and will no longer be available. It has now been replaced by uPAC-7186EG and uPAC-7186EGD.

The μPAC-5x07(P) series is a palm-size programmable automation controller. It has a 80186 CPU, SRAM, Flash, Ethernet port, RS-232 and RS-485 port. With a DOS-like OS (MiniOS7) and a developed firmware running inside, it can act like a small PC. 

For hardware expansion, it also supports an I/O expansion bus. The I/O expansion bus can be used to implement various I/O functions such as DI, DO,A/D, D/A, Timer/Counter, UART, and other I/O functions. Nearly all kinds of I/O functions can be implemented by this bus. The bus can support one board. There are more than 10 boards available for μPAC-5x07(P) series, you can choose one of them to expand hardware features.

μPAC-5x07(P) is the model of μPAC-5x07 with PoE (Power-over-Ethernet). PoE allows power and data to be carried over a single Ethernet cable, so a device can operate solely from the power it receives through the data cable. This innovation allows greater flexibility in office design, higher efficiency in systems design, and faster turnaround time in systems design, and faster turnaround time in set-up and implementation.

Communication Interface

The uPAC-5x07(P) provides Ethernet solutions. It contains 3 communication ports, COM1: RS-232, COM2: RS-485, Ethernet port: 10/100 Mbps Ethernet. These different communication ports can provide various kinds of usage include RS-485 networking, controller to controller data-exchange, Modbus RTU/ASCII Master Protocol, Modbus RTU/TCP Slave Protocol, Remote I/O extension, linking with HMI/MMI, program download/upload, and debugging.

Communication Interface

Modbus RTU/TCP Slave Ports

Modbus RTU (RS-232/485/422): max. 2 Modbus RTU Slave ports

Modbus TCP/IP: max. 6 Modbus TCP Slave connections

Modbus RTU/TCP Slave

Modbus RTU/ASCII Master Ports

Modbus RTU/ASCII (RS-232/485/422): max. 2 Modbus RTU/ASCII Master ports.

Modbus RTU Master

Multi-Client Connection

Each uPAC-5x07(P) has an IP address and with a fixed port No. of 502. With Modbus TCP/IP protocol, up to 6 PCs can link to one uPAC-5x07(P) through Ethernet. With Modbus serial protocol, another PC or MMI can link to the  COM1 (RS-232) port of the μPAC-5x07(P). Therefore, the maximum number of clients that can be linked is 7.

Expansion Boards and Remote I/O Modules

RU-87Pn Features

Hot Swap

Auto-Configuration - Configurations of I-87K I/O modules can be pre-configured and stored in the nonvolatile memory of the RU-87Pn.

Easy Duplicate System- Using the DCON Utility, you can easily make a backup of the I-87K module configurations and write to another RU-87Pn.

Full Software Support - The free-of-charge software utility and development kits are included.

Remote IO

I/O Expansion Boards

The uPAC-5x07(P) has an I/O expansion bus which can plug One I/O expansion board.

Linking the I-7000 & I-87K module for Remote I/O

The uPAC-5x07(P) PAC can use its COM2 (RS-485) port to link to ICP DAS's "I-7000" & "I-87K" series of Remote I/O modules. This configuration can be very useful in applications that require distributed Remote I/O throughout the system. 


Data Exchange: Fbus & Ebus

Fbus ( RS-485 Network )

Each uPAC-5x07(P) can use its RS-485 port (COM2) to talk to each other via the Fbus communication mechanism. Fbus can be used to broadcast data to each controller or each controller can request to send or receive data from any other controller on the same Fbus network.

Ebus ( Ethernet Network)

Each uPAC-5x07(P) can use its Ethernet port to talk to each other via the Ebus communication mechanism. When PC is talking with controllers via Ethernet, the controllers can also talk to each other via the same Ethernet; It makes the configuration more flexible and faster.

Data Exchange

Data Log

ICP DAS provides a freeware “UDLoader.exe” to load the data stored in battery-backup SRAM via RS-232 or Ethernet port.

Redundancy Solution Two PACs plug with XW107 in slot0. One is Master, one is Slave. Master handles all inputs & outputs at run time. If Master is damaged (or power off), Slave will take over the control of Bus7000b. If Master is alive from damaged (or power up again), it takes the control of Bus7000b again. The change over time is about 5 seconds. Control data is exchanging via Ebus (if using a cross cable, no require any Ethernet Switch). All I/O should be RS-485 I/O except the status I/O in the slot 0: XW107.
