7 Display
The CCP 621 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. "Er" (error) and the error code thereby alternate in the
display. 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.
