Display
The CCP 521 processor module has a 2-digit decimal display (7 segment display) for the
following functions:
- When configuring the processor module, the parameters are shown in the display.
- If an error occurs while running the program or no valid user program is found, the dis-
play shows an error message. Thereby, "Er" (error) and the error code are displayed al-
ternatingly. The same error code is also shown in the LASAL status line.
- While running the program, the display can be used to show digits using the system
variable _cpuDisplay. Valid values are 0 to 255; values over 99, however, are not shown
and the display remains dark.
