Run Tests under the System Setup Screens
Use the
C-more
6” Micro-Graphic panel’s System Setup Screens to test communication ports,
PLC connectivity, the internal beeper and touch screen operation. See
Chapter 5: System Setup
Screens
for additional details.
Serial Port1
- Performs a test to verify the RJ12 serial communications port (Port 1) on the
panel is operating correctly. Requires a loop back connector inserted into the port to properly
run the test. A wiring diagram for the loop back connector is shown below.
Serial Port2
- Performs a test to verify either the RS-232 or the RS485/422 serial
communications functionality from the 15-pin connector (Port 2) on the panel is operating
correctly. A loop back connector inserted into the port is required for proper testing. Wiring
diagrams for RS-232 and RS-485/422 loop back connectors are shown below.
PLC Enquiry Test
- Tests the communications with the selected PLC protocol between the
panel and a connected PLC. Is used with both Port1 and Port2.
Buzzer Test
- Use this option to test the internal audible beeper of the panel.
Touch Panel Test
- Tests the response of the touch screen area to contact. This test is used to
make sure the touch screen area is responding properly.
NOTE: Only one
of the ports can be used with a connected PLC. The programming software allows the user
to select either Port1 or Port2 under the Panel Manager dialog box. When using Port2 to communicate with
the connected PLC, Port1 can still be used with the EA-MG-PGM-CBL Software Programming Cable
Assembly to transfer projects between the PC and panel.
