YASKAWA JANCD-XCP0101C-1 Control protection module

The PLC generates an image of the input signals planned in the PLC program at the start of each program cycle. If inputs are to be forced, their real values are replaced by the force values preset by the user after read–in. The PLC operates only with the modified input image during the program cycle, and, thus, signal changes on the input device during the program cycle are unimportant.

At the end of the program cycle, the PLC transfers the output image of the output signals planned in the PLC program to the output devices. If outputs are to be forced, their real values are replaced by the force values before they are output in the output image. Behavior after power failure, RESET or warm–start After a power failure, the PLC has ”forgotten” the force job. The list of I/O signals to be forced, entered before the power failure, is, however, still present in the PLC and can also be displayed with command FORC A. The overall force list is reactivated and forcing is placed back into effect by entering a single signal to be forced.

Delete forcing

Function:
Displaying all inputs and outputs to be forced
Displaying all inputs/outputs of a specific group of inputs/outputs to be forced Note on service device TCZ: This command can be used only with the following restriction: A maximum of three I/O signals with related force values can be displayed on the liquid–crystal display (LCD).

name: Name of the inputs/outputs for which forcing is to be terminated ;: If forcing is terminated only for specific inputs/outputs, the individual names must be separated by a semicolon when entering them. Function: (1) Terminating forcing for all I/O signals (2) Terminating forcing for single I/O signals (3) Terminating forcing for one specific group of I/O signals

Perform cold–start

The cold–start command is only allowed, when the PLC program is ”aborted”. – All RAM memories will be tested and deleted. – If there is no user program in the Flash EPROM, the default values will be set to all system constants (same as factory setting). – If there is a user program in the Flash EPROM, this will be stored in the RAM inclusive the system constants. – The operating modes defined by the system constants will be adjusted. – The CS31 system bus will be initialized again (only in case of CS31 system bus master) Performing a cold start – Command KALTin terminal mode or – Voltage OFF/ON, when no battery is existing or – menu item ”Kaltstart” in the programming system

Performing a warm start – Command WARMin terminal mode or – Voltage OFF/ON, if a battery is existing or – menu item ”Enable PLC mode” in the programming system
