Enums ¶ AREA_TYPE (Enum) ERROR (Enum) PLC_IDENT (Enum) STATE (Enum)

AREA_TYPE (ENUM) ¶ TYPE AREA_TYPE : Redundancy area type Attributes: qualified_only InOut: Name Comment AREA_NONE None AREA_INPUT Input - synchronized once at boot up of second PLC. Areas are registered automatically according settings in redundancy configuration, area settings dialog AREA_SYNCHRO Synchro - synchronized each task cycle start, data copied from active to standby PLC in each cycle. Note size is limited AREA_OUTPUT Output - not synchronized, only crc check is done AREA_PASSIVE Passive - copied from passive to active controller before writing outputs. Note size is limited

ERROR (ENUM) ¶ TYPE ERROR : Attributes: qualified_only InOut: Name Comment NO_ERROR No error ERROR nonspecific error RDCY_BOOTUP_ERROR Error occured during boot up RDCY_SYNCHRO_ERROR Error occured during synchronisation RDCY_CYCLE_ERROR Error occured at cycle start or end - communication error RDCY_LINK_ERROR Error with redundancy link - not connected RDCY_FIELDBUS_ERROR Error reported by fieldbus RDCY_RECEIVEMESSAGE_ERROR Error in receiving a message RDCY_NOMESSAGE_ERROR No message received RDCY_WRONGMESSAGE_ERROR Wrong message received RDCY_CONFIG_ERROR Configuration error RDCY_INPUTAREACRC_ERROR Input area crc on both plcs does not match RDCY_NO_LICENSE_ERROR No valid license found

PLC_IDENT (ENUM) ¶ TYPE PLC_IDENT : Identification of the PLC, independent from active or passive plc state. Attributes: qualified_only InOut: Name Initial Comment PLC_ID_NONE 0 Not specified. Setting in cfg file missing - write settings to plc PLC_ID_1 1 PLC 1 PLC_ID_2 2 PLC 2
