Uni-COM I/O Modules: Status and Error Messages

Each I/O module data tag struct contains tags that are dedicated to error/status messages.

The values listed below are given in hexadecimal.

Notes

Each module contains a 32-bit IO - Status tag. A value of 0x00 = No Errors.
If the error message is to Contact Support, supply the specific error code to the support team.
Note that LED indications are provided below.
The file Connected_IOs_Module_Data.csv. is created by the controller at powerup and placed on the root of the SD card. The file contains data regarding any Uni-I/O modules connected to the controller. The data includes the position relative to the controller, model, serial number, and operating system version numbers of the of the Uni-I/O module
IO Bus Error screenIO Bus Error screen

At powerup and HMI reset, if the system detects IO bus errors, the following screen will be displayed showing the error code.

Codes

0 - OK

1 - Connectivity / Wiring problems

2 - IO configuration mismatch – type mismatch: the UniLogic Hardware Configuration contains an IO module of a model different from the modules actually connected to the controller

3 - IO configuration mismatch – number mismatch: for example the UniLogic Hardware Configuration contains 2 IOs, but 3 are actually physically connected.

4 - Unitronics – IO exists, but returns an unexpected answer during IO initialization.

5 - A specific IO is faulty, check the IO after the last I/O listed in the table.

Over/Under flow

Note

Overflow or Underflow is when an input value exceeds the Over-range or Under-range boundaries respectively.

Input Overflow:
The module measures values that are up to 1.5% higher than the nominal input range (i.e. Input Over-range) It can output values that are up to 1.5% higher than the nominal output range (Output Over-range).

Note that when input overflow occurs, it is indicated in the Status Input Channel tag: Bit 2 will be ON, while the input value itself will show the maximum permissible value.

For example, if the specified input range is 0–10V, the Over-range values can reach up to 10.15V.
If, for example, Input 1 reaches levels exceeding 10.15V, in the Status Input Channel tag, both Bit 2 Input Overflow and Bit 4 Input Over-range will turn ON. At the same time, in the Input Struct, the data tag Input 1 will show the maximum value of 10.15V, although the actual value exceeds this.

Temperature Inputs:
Temperature inputs measure values that are slightly higher or lower than the nominal input range (Input Over/Under-range respectively). Note that when input Overflow, Underflow or a connection fault occurs, it is indicated in the corresponding I/O Status tag (refer to the UniLogic™ help for details) as well as by the respective input LED (see LED Indications), while the input value is registered as follows:

Fault Type	Registered Value in the Input Tag
Overflow	32,767
Underflow	-32,767
Connection fault	-32,768

Output Under/Overflow

The module's analog outputs are able to output values that are slightly higher or lower (if applicable) than the nominal output range (Output Over/Under-range respectively).
