Place this address into an index register and useindirect addressing through the index register to read the communicationscompletion code.Stores the communications port numbers used when a communicationsinstruction is executed using automatic communicationport allocations.0000 to 0007 hex: Communications port 0 to 7ON when an error occurred during execution of a network instruction(SEND, RECV, CMND, or PMCR).Bits 00 to 07 correspond to communications ports 0 to 7.ON: Error occurredOFF: Normal conditionThese words contain the actual input response times.0 to 17 hexadecimalWhen the Basic I/O Unit input response time setting is changed inthe PLC Setup while the PLC is in PROGRAM mode, the settingin the PLC Setup will not match the actual value in the Basic I/OUnit unless the power is turned OFF and then ON again. In thatcase, the actual value can be monitored in these words.Indicates the current status of I/O allocation, i.e., Automatic I/OAllocation or User-set I/O Allocations.0000 hex: Automatic I/O allocationsBBBB hex: User-set I/O allocationsON: Error in CPU Bus Unit SetupTurns OFF when I/O tables are generated normally.ON: Error in CPU Bus Unit SetupOFF: I/O tables generated normallyA261.02 ON: Overflow in maximum number of I/O pointsTurns OFF when I/O tables are generated normally.ON: Overflow in maximum number of I/O pointsOFF: I/O tables generated normallyA261.03 ON: The same unit number was used more than once.Turns OFF when I/O tables are generated normally.ON: The same unit number was used more than once.OFF: I/O tables generated normallyA261.04 ON: I/O bus errorTurns OFF when I/O tables are generated normally.ON: I/O bus errorOFF: I/O tables generated normallyA261.06 ON: I/O table error because a SYSMAC BUS Slave cannot bedetectedTurns OFF when I/O tables are generated normally.ON: SYSMAC BUS Slave missingOFF: I/O tables generated normallyA261.07 ON: Error in a Special I/O UnitTurns OFF when I/O tables are generated normally.ON: Error in a Special I/O UnitOFF: I/O tables generated normallyA261.09 ON: I/O detection has not been completed.Turns OFF when I/O tables are generated normally.ON: I/O detection has not been completed.OFF: I/O tables generated normally--- Maximum CycleTime (0.1-msincrements)FunctionThese words contain the maximum cycle time since the start ofPLC operation.
