Master And Slave
Smart I/O
-
An I/O server is a software which controls and monitors one or more PLCs /RTU's using various communication protocols.Our I/O servers are built on highly optimized Windows 32bit platform. They are capable of handling very large scale SCADA systems with minimal impact on CPU usage, resulting in effective timing and usage of available hardware.Currently, we have Master and Slave solutions for DNP3 and Modbus (ASCII, RTU, TCP). Please select the appropriate tab above for more informaiton.If you are looking for a specific I/O Server, please contact us with your needs.

Modbus-RTU I/O Modules
-
Sophisticated watchdog timer functions allow the application to define the module's failsafe output state. The watchdog timer invokes the failsafe condition when communication between the host and module exceed a duration specified by the application. For further security, a second hardware watchdog timer monitors the microcontroller for failed operations or a "lock-up" condition and automaticaly resets the unit.
