Address
A640.00 Turn ON this bit to send a command and receive a
response for serial port 2 using the Modbus-RTU easy
master function.
This bit will be turned OFF automatically by the system
when communications have been completed.
Turned ON: Execution started
ON: Execution in progress.
OFF: Not executed or execution completed.
A640.01 ON when one command has been sent and the
response received for serial port 2 using the Modbus-
RTU easy master function.
ON: Execution normal.
OFF: Execution error or still in progress.
A640.02 ON when an error has occurred in communications for
serial port 2 using the Modbus-RTU easy master func-
tion. The error code is output to D32252 in the DM fixed
allocation words for Modbus-RTU Easy Master.
ON: Execution error.
OFF: Execution normal or still in progress.
Address
A200.12 ON for one cycle when step execution is started with
STEP(008).
A600 to Before the subroutine specified in MCRO(099) is exe-
A603 cuted, the source words for the subroutine are trans-
ferred to A600 through A603 (input parameter words).
A604 to After the subroutine specified in MCRO(099) has been
A607 executed, the results of the subroutine are transferred
from A604 through A607 to the specified destination
words (output parameter words).
Address
A345.00 Turns ON if the FB program memory contains FB pro-
gram data.
OFF: No data
ON: Data present
Address
A580.15 0: Not required
1: Required
A580.08 to 0 to 7 hex: Communications port No. 0 to 7
A580.11 F hex: Automatic allocation
A580.00 to Automatically stores the number of retries in the FB com-
A580.03 munications instruction settings specified in the PLC
Setup.
A581 Automatically stores the FB communications instruction
response monitoring time set in the PLC Setup.
0001 to FFFF hex (Unit: 0.1 s; Range: 0.1 to 6553.5)
0000 hex: 2 s
A582 Automatically stores the FB DeviceNet communications
instruction response monitoring time set in the PLC
Setup.
0001 to FFFF hex (Unit: 0.1 s; Range: 0.1 to 6553.5)
0000 hex: 2 s
