● Type 4 with calculation at block end point● Type 5 automatic start of the selected program point with calculation of all required datafrom history● Automatic start of an ASUB after a block search● Cascaded block search● Cross-channel block search in "Program test" modeProgram operationThe execution of part programs or part program blocks in AUTOMATIC or MDI modes isreferred to as program operation. During execution, the program sequence can be controlledby PLC interface signals and commands.For each channel, basic settings or channel-specific machine data can be specified. Theseinitial settings affect, for example, G groups and auxiliary function output.A part program can be selected only if the relevant channel is in the Reset state.Furthermore, all further program runs are handled by PLC interface signals and thecorresponding commands.● Start of part program or part program block● Part program calculation and program control● RESET command, program status, and channel status● Responses to operator and program actions● Eventdriven program callsAsynchronous subroutines (ASUBs), interrupt routinesInterrupt inputs allow the NC to interrupt the the current part program execution so that it canreact to more urgent events in interrupt routines or ASUBs.Single blockWith the single-block function, the user can execute a part program block-by-block.There are 3 types of setting for the single-block function:● SLB1: = IPO single block● SLB2: = Decode single block● SLB3: = Stop in cycleBasic block displayA second basic block display can be used with the existing block display to display all blocksthat produce an action on the machine.The actually approached end positions are shown as an absolute position. The position valuesrefer either to the workpiece coordinate system (WCS) or the settable zero system (SZS).K1: Mode group, channel, program operation, reset response9.1 Product briefBasic Functions456 Function Manual, 01/2015, 6FC5397-0BP40-5BA2
