Address
A641.00 Turn ON this bit to send a command and receive a
response for serial port 1 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.
A641.01 ON when one command has been sent and the
response received for serial port 1 using the Modbus-
RTU easy master function.
ON: Execution normal.
OFF: Execution error or still in progress.
A641.02 ON when an error has occurred in communications for
serial port 1 using the Modbus-RTU easy master func-
tion. The error code is output to D32352 in the DM fixed
allocation words for Modbus-RTU Easy Master.
ON: Execution error.
OFF: Execution normal or still in progress.
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
A597 When a data register is specified as the output for an
instruction processed in the background, A597 receives
the output instead of DR00.
0000 to FFFF hex
A595 and When an index register is specified as the output for an
A596 instruction processed in the background, A595 and A596
receive the output instead of IR00.
0000 0000 to FFFF FFFF hex
(A595: Rightmost digits, A596: Leftmost digits)
