MXP Diagnostic Terminal

 

8.1 MXP DIAGNOSTIC TERMINAL OPERATION

8.1.1INTRODUCTION

The MXP provides diagnostic functions via its serial port (J5) with a terminal or PC connected. Commands may be entered which :

Display the analogue values (Raw values, Filtered values, etc) of selected devices.

Select devices for such display.

Display and reset error counters.

Determine all the devices and their types, as seen from each end of the loop.

Change an addressable device’s address.

Perform advanced diagnostics.

The MXP diagnostic serial port operates at 19200 baud, 8 data bits, no parity, 1 stop bit. A 3-wire cable is needed and it is wired the same as the MX4428 FIP programming terminal cable. This needs either a DB9 or DB25 connector and can be ordered as fully assembled cables using part numbers LM0042 (DB25) and LM0041 (DB9).

To utilise the colour logging facility an ANSI terminal emulator mode is required. Hyperterm and Accuterm are suitable for Windows and Procomm is suitable for DOS. For simple applications where logging to disk and scroll-back are not required mxpprog32 can be used with Windows and mxpprog can be used with DOS – these are included in SF0250.

8.1.3 SELECTING POINTS FOR MONITORING

Before the MXP can display analog values received from points, the user must select the points to be monitored (i.e. include in the monitoring list). This is done using the following commands –
