This I/O Server also supports the legacy PortBox, ER84 and ER88 conrollers.

HSYCO Configuration

Add an HWGIO I/O Server in the I/O Servers section of the Settings and set its parameters:


  • IP Address: host name or IP address of the I/O Controller
  • IP Port: TCP/IP port to use, leave blank to use default port 23.

High Availability

  • Shutdown when inactive: defaults to true (the I/O Controller only accepts one connection and can't be accessed by two HSYCO servers simultaneously).


There are no available configuration options for the HWGIO I/O Server.

I/O Controller Configuration

TCP/IP mode needs to be configured and NVT (Network virtual terminal) enabled in order to work with the digital inputs and outputs.

Refer to the I/O Controller manual for detailed configuration information.


The data points associated to the input pins are named “i1” to “i8”.

The data points associated to the output pins are named “o1” to “o8”.

The I/O Server generates asynchronous events based on the status of the I/O Controller's input and output pins. The output data points can be written to control the output pins.

ID Value R/W Description
i<n> 0 R input <n> is low
1 R input <n> is high
o<n> 0 R output <n> is low
W set output <n> to off
1 R output <n> is high
W set output N to on
