The central unit is set to ”Stand-alone” upon delivery. Changing the application mode is carried out in the following three steps: 1. Change the system constant KW 00,00 in the PLC, see chapter A7.3 (Appendix), System constants 2. Save the user program in the Flash EPROM 3. Activate new application mode by: – calling up the menu item of ”Enable PLC mode” in the ABB programming and test system or – performing a warm start or – performing a cold start. Setting the cycle time see chapter A1 (Appendix), Processing times Addressing when remote modules are connected see chapter A2 (Appendix), Addressing Back-up of data areas Back-up of data areas, i.e. saving of data during power OFF/ON, is only feasible with built-in battery. The following data can be backed, completely or partly: – Binary flags – Word flags – Double word flags – Step chains – Historical values In order to back-up certain data, they have to be excluded from initialization to 0.
During program start, that data areas are initialized to 0 partly or completely, that are defined by system constants, see chapter A7.3 (Appendix), System constants. If no battery is effective or if the system constants are in their default values (factory settings), all of the above mentioned data areas are completely set to 0 after power OFF/ON. Reactions on errors of error class 3 The user can configure whether or not the user program is to be aborted automatically, if an class 3 error occurs, see chapter A7.3 (Appendix), System constants. Starting-up the CS31 system after power ON The user can enter a number of n remote modules in KW 00,09. The user program starts only, i.e. it handles process inputs and outputs only, if at least n remote modules have been adopted into the CS31 system bus cycle, see chapter A7.3 (Appendix), System constants.
The earthing measures The handling of the electrically isolated input groups The handling of the electrically isolated output group The connection of analog-value receiver and analog-value sensor The earthing of the switch cabinet mains socket 2.3.2 Connecting the supply voltage The 24 V DC supply voltage is connected via a 5-pole detachable terminal block. Attention: Plug and unplug terminal block only with power is off!
Electrical isolation and notes on earthing The following illustration shows the parts of the device’s circuit which are electrically isolated from each other as well as the internal connections which exist. Both the creepage distances and clearances as well as the test voltages used correspond to DIN/VDE 0160. The 6.3 mm Faston terminal in the lower left corner has to be connected directly and on the shortest possible way to the switch cabinet earthing using a wire with a cross section of 6 mm2 in order to ensure safe earthing and as an EMC measure.
see also chapter A8 (Appendix) The ARCnet coupler is integrated in the central unit 07 KT 92 R262. The DIL switch for setting the ARCnet address is accessible through the cutout of the external networking interface. The ARCnet coupler is supplied from the internal 24 V DC power supply. Important note: If a PLC is used with an ARCnet interface, a certain section of the PLC TURBO program memory No. 2 is reserved for ARCnet. If programs with more than 2 k instructions are executed, the system-dependent capacity utilization can possibly be increased by reason of the reduced TURBO memory No. 2 when changes are made to a running program. There are no problems, if the capacity utilization is less than 80 % before making changes to a running program or if the program length is less than 2 k instructions. The function blocks AINIT, ASEND, AREC and APOLL are available for the ARCnet coupling.
