Troubleshooting

The HMI must be connected to a PLC/controller in order for the project to run correctly in the HMI. If there is a

problem with communications between the HMI and PLC/controller, the “PLC no response” message (window 5) will

appear on the screen and objects addressing PLC registers will not appear on the screen. Here are some things to

check if this occurs:

1. Make sure you have selected the correct communication protocol (driver) for the PLC you are using in the

System Parameters (Edit > System Parameters > Device Properties).

 The demo version of EasyBuilder-5000 will not download the driver to the HMI and will automatically

generate a “PLC no response” error message.

2. Make sure the communication settings in the HMI (Edit > System Parameters > Device Properties) match the

communication settings in the PLC.

3. Make sure the communication cable is wired correctly for your application. Refer to the Controller Cable

Assembly drawings on our website for specific cabling information for your PLC/controller.

4. Check the address formatting for objects that are reading from or writing to registers in the PLC. If the

objects cannot access specific registers in the PLC, they will not appear on the screen. Refer to the Controller

Information Sheet for your particular PLC/controller for specific information about accessible registers in the

PLC memory and the correct addressing format for the various registers.
