Communication

The I-8437 / 8837 provides ethernet solutions. It contains 4 communication ports, COM1:RS232, COM2: 10M ethernet , COM3:RS232/RS485, COM4:RS232.

The I-8417 / 8817 provides RS485 solutions. It contains 4 communication ports, COM1:RS232, COM2: RS485, COM3: RS232 / RS485, COM4:RS232.

These different communication ports can provide different kinds of usage include RS485 networking, controller to controller data-exchange, Modbus / Modbus TCP protocol, remote I/O extension, linking with HMI / MMI, program download / upload , and debugging.

Modbus & Modbus TCP/IP

Modbus is a widely used communication protocol. The I-8417 / 8817 supports Modbus RTU protocol on RS232 (COM1) and RS485 (COM2). The I-8437 / 8837 supports Modbus RTU protocol on RS232 (COM1) and Modbus TCP/IP protocol on Ethernet (COM2).

Any HMI (for example, Iconics, Intouch, FIX, Citect, Wizcon, Labview, Lablink, ...), Modbus OPC server, touch monitors (for example, The Touch 506, Touch 509, Touch 510) or other MMI devices can easily talk with the I-8xx7 by Modbus protocol. It is easy to find software and devices with the Modbus protocol on the market. Or, by using VB, VC programming, users can design software with Modbus protocol to talk with the controller.

Modbus Master

The COM1 and COM2 of I-8417/ 8817/ 8437/ 8837 are Modbus slave ports. PC and HMI are the Modbus master and talk with the Modbus slave port of COM1 or COM2 of the controllers. Moreover, I-8xx7 can also provide Modbus Master protocol on either  COM3 or COM4 of the controllers, in order to talk to devices with Modbus slave protocol, such as PLC, RTU, power meterˇK

Multi-client Connection

Each I-8437 / 8837 has an Ethernet port and can take your control system to Internet world. Each I-8437 / 8837 has an IP address and with a fixed Ethernet port No. of 502. Up to 5 PCs can link to one I-8437 / 8837 through Ethernet. Another PC or MMI can link to COM1: RS232 port of the I-8437/ 8837. Therefore, the maximum number of clients that can be linked is 6.

For the I-8417/ 8817, the maximum number of clients that can be linked is 2, one linking to COM1: RS232 and the other linking to COM2: RS485.

RS485 Network

One PC or HMI can link to one I-7520 converter to talk to a maximun of 255 I-8417 / 8817 controllers on a RS485 network. The I-8417 / 8817 uses COM2:RS485 as its RS485 network port. Each controller on the same RS485 network should set its unique NET-ID to make networking smooth and error-free. The max. distance can be up to 1200 meters with the terminal resistors.

Data Exchange via Fbus or Ebus

Fbus ( RS-485 network )

Each I-8xx7 can use its other RS-485 port ( COM3 ) 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 8437 / 8837 can use its ethernet port ( COM2 ) to talk to each other via the Ebus communication mechanism. When the PC is talking with controllers via ethernet, the controllers can also talk to eachother via the same Ethernet, It makes the configuration more flexible and faster.

Sending Email

The ISaGRAF driver inside the I-8417 / 8817 / 8437 / 8837 provides ˇ§Emailˇ¨ function block to send email form the COM4 of the controller via a general modem. Then it will be an useful and easy way to send an alarm message to the system operator. Or it can becom a production report system.

Various IO boards / Remote IO Extension

The I-8417 / 8437 provides 4 empty slots while the I-8817 / 8837 provides 8 empty slots on-board. The IO boards include Digital I/O, Relay output, SSR-DC/AC output, AC input, Strain Gauge input, Analog I/O, RTD, Thermocouple, counter,  frequency, and more. There are more than 30 different I/O boards available now and, in the future, there will be more. The max.  channel provided by the I-8040 / 8041 / 8042 Digital I/O boards is 32.

Remote IO modules are useful for some distributed applications. The I-8417 / 8817 / 8437 / 8837 can integrate with the I-7000 and I-87xx modules by linking one of its COM3 or COM4 ports to each remote I/O module. A max. number of 64 remote I/O  modules can be linked to one controller and max. number of 16 I/O channels for some remote I/O modules.

Remotely Download Program: Modem_Link

The Mode_Link is an software designed by ICP DAS, which need to be installed into the ISaGRAF software in your PC. The Modem_Link provide you a easy way to remotely download your ISaGRAF program to the I-8417/ 8817/ 8437/ 8837 via a general modem. And also you can monitor every I/O, data and if the program allows, you can controll it via the Modem.
