The I-8437-80/8837-80, I-8417/8817 is an ISaGRAF PAC and includes ISaGRAF SoftLogic, ISaGRAF is a Windows programming tools and also provides powerful debugging tools including On-line Motoring and Control and also Off-line Simulation. There are more than 300 function blocks built-in the PAC for various Industrial Applications including PID, motion, remote IO, serial communication, SMS, retain variable, scaling, etc.
In hardware, I-8xx7 has 3 or 4 serial ports, support Modbus RTU slave protocol and it can easily communicate with PC/HMI/OPC Server and Touch panel. The I-8xx7 also supports up to 2 COM ports of Modbus RTU / ASCII master protocol to integrate with other Modbus devices. The I-8x37-80 has one 10M Ethernet port.
The I-8xx7 supports various High/Low profile I/O modules. The user can choose Local I/O modules:I-8K/I-87K I/O modules and RS-485 Remote I/O modules:I-7000 or expansion units (I-87Kn or RU-87Pn) plugged with I-87K serial I/O modules. Compared to I-8437/8837 (It has phased out), I-8x37-80 is 2 ~ 4 times faster!
All remote I-7000 I-87K DI modules support counters. 100Hz max. value: 0 to 65535
High Speed Counter
I-87082: 100 kHz max. 32 bit I-8080: 450 kHz max. 32 bit
Protocols
Modbus Slave Protocol
COM1 COM2 default support Modbus RTU Slave protocol for connecting ISaGRAF, PC/HMI/OPC Server MMI panels.
Modbus Master Protocol
Up to 2 COM ports (COM1, 3, 4 or COM5 if multi-serial port boards are plugged) support Modbus master protocol to connect to other Modbus slave devices
Remote I/O
One of COM3 or COM4 supports I-7000 I/O modules (I-87K base + I-87K serial I/O boards or RU-87P1/2/4/8 + I-87K High Profile I/O cards) as Remote I/O. Max. 64 Remote I/O modules for one controller.
Fbus
Built-in COM3 Port to exchange data between ICP DAS's ISaGRAF PACs
SMS: Short Message Service
One of COM4 or COM5 can link to a GSM modem to support SMS. User can request data/controller by cellular phone. The controller can also send data alarms to user's cellular phone. Optional GSM modems: GTM-201-RS232 (850/900/1800/1900 GSM/GPRS External Modem).
User-defined Protocol
User can write his own protocol applied at COM1, 3, 4 ( COM5 ~ 20 if multi-serial port boards are plugged) by serial communication function blocks
Modem Link
Supports PC remotely download monitor the controller through a normal modem.
MMICON / LCD
One of COM3 or COM4 supports ICP DAS's MMICON. The MMICON is featured with a 240 x 64 dot LCD and a 4 x 4 Keyboard. User can use it to display picture, string, integer, float, and input a character, string, integer and float.
Redundant Bus7000
Two ISaGRAF controllers can link to remote I-7000 I-87K I/O modules at the same time. Only one controller is active to control these remote I/Os. If one is dead, the other one will take over the control of remote I/Os.
Battery backup SRAM
Supports up to 1024 retain variables with a S256/S512 plug in the socket of the back-plane. Data can also be stored in the S256/S512, and then PC can load these data via COM1 or COM2. PC can also download pre-defined data to the S256/S512. Optional: S256: 256 KB, S512: 512 KB
