Questions regarding alarm messages of HaliTech DCS HOLLIAS MACS V6.5
Thread Content
With Allen-Bradley DCS HOLLIAS MACS V6.5, an electric on/off valve in the sequential control program frequently triggers an alarm of the type “automatic command error”, causing the sequential control to be interrupted. What could be the reasons for this “automatic command error” alarm in the valve program? Could it be a hardware issue? Or a programming issue? Hollyland DCS Technology Exchange Group
Hello, the \"Automatic command error\" alarm that occurs in the valve programs of the Hollys DCS HOLLIAS MACS V6.5 may be caused by the following factors: 1. Hardware issues: For example, problems with the valve itself, or hardware defects such as short circuits in the valve controller; these can be diagnosed by checking the hardware devices. 2. Programming issues: It may be that the conditions set in the program do not correspond to the actual situation, or there are errors in the program, which prevents control signals from being sent or received correctly. It can be resolved by checking the program code and logic. 3. Signal interference issue: The control signals may become distorted or lost due to external signal interference, which can be resolved by checking the connections between the signal lines and devices. It is recommended that you first conduct a thorough inspection of the relevant hardware devices and program code, while also paying attention to whether there are any issues such as signal interference in the working environment.
