Introduction
The Catalyst is very well suited to be interfaced to the Automation Direct Terminator I/O (T1K) distributed I/O product. However, there are a few changes that need to be made from the default configuration of each product.
Note: This document will refer to certain pages of the T1K User Manual. Please have the manual available when you are ready to make settings changes.
Setting the Catalyst Protocol Port Parameter
The Catalyst Protocol Port is configured for either Ethernet or Modbus. When Modbus is chosen, the Catalyst will be configured for "Even" Parity by default. In order to communicate with the T1K, you will need to change the Parity setting to "Odd."
To make the necessary change using Alarmware™, connect to the unit and go to the "Configuration Menu." From the Configuration Menu, select "Devices." Click on the "Protocol Port" tab. The following dialog will appear:
Terminator I/O Base Controller Settings
Most of the Terminator I/O Base Controller settings will be left in their default settings, with the following exceptions:
Modbus Address Mapping (Also applicable for ModbusTCP)
Please refer to pages 3-4 of the "T1K Modbus Base Controller User Manual" for the technical details of the T1K Modbus 584/984 addressing.

Special Note: Analog points occupy 2 consecutive 16-bit integers, but the second of the two are not used. Therefore, the first analog point address is 30001. The second is 30003. The third is 30005, and so on.

The special note above for analog inputs also applies to analog outputs.
* SNA refers to "Source Net Address" for the Catalyst Channel Setting.
Catalyst Scaling for Terminator I/O Analog Channels
The resolution of Terminator I/O analog points is 14 bits (13 bits plus the sign bit) for inputs, and 12 bits for analog outputs.

Please Note:
Analog Scaling
Scaling to engineering units will depend on the application (water tank level, etc.). Use Alarmware™ to configure your channel settings by first connecting with the Catalyst unit. From the "Configuration" menu, select "Channels." To read a voltage input directly in volts, do the following:
X1=0 |
Y1=0 |
X2=8191 |
Y2=10 |
To read a current input directly in mA, do the following:
X1=0 |
Y1=0 |
X2=8191 |
Y2=20 |
