ZigBee Wireless Solution
ISaGRAF PAC plus ZB-2550P and ZB-2551P (ZigBee to RS-232/485 Converters) can apply wireless communication, reduce the wiring cost, and achieve the mission of remote I/O control and data acquisition.
ICP DAS releases effective VW sensor solution (Vibration Wire solution). It’s useful for measuring the stress of constructions like building, bridge, dam, etc...
This solution has been successfully applied in some water dams monitoring system near the city Wuhan in China.
The I-8xx7 can support various communication specifications. These different communication ports can provide different kinds of usage include RS-485 networking, controller to controller data-exchange, Modbus/Modbus TCP protocol, Remote I/O extension, linking with HMI/MMI, program download/upload, and debugging.
Each I-8437-80/8837-80 has an IP address and with a fixed Ethernet port No. of 502. With Modbus TCP/IP protocol, up to 4 PCs can link to one
I-8437-80
/8837-80. With Modbus RTU Slave protocol, another PC or MMI can link to the COM1 (RS-232) port of the I-8437-80/8837-80. Therefore, the maximum number of clients that can be linked is 5.
For the I-8417/8817, the maximum number of clients that can be linked is 2, one linking to COM1: RS-232 and the other linking to COM2: RS-485.
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.
RS-232/422/485 Expansion Modules
The I-8xx7 can plug a RS-232/422/485 expansion module. Available modules are as I-8112/8114/8142/8144/8142i module.
Linking the I-7000 & I-87K Module for Remote I/O
The I-8417/8437-80 provides 4 empty slots while the I-8817/8837-80 provides 8 empty slots on-board. There are about 100 choices of I/O local boards & remote modules.
Remote I/O modules are useful for some distributed applications. The I-8417/8817/8437-80/8837-80 can integrate with the I-7000 and I-87K 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. ( How to use ? )
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 I-8437-80/8837-80 can use its Ethernet port (COM2) 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.
The Modem_Link is a software designed by ICP DAS, which needs to be installed into the ISaGRAF software in your PC.
