Remedy
1. Check whether there is noise, and retry the sending of
the command.
2. Check whether the slave operates normally.
Make sure that the format of the command conforms to
the ASCII format.
Check whether the slave operates normally, and whether
the connection is normal.
1. Check the program and the related special data
registers.
2. Set the communication port parameter for the CPU
module in HWCONFIG again.
Check whether the slave operates normally, and whether
the connection is normal.
Check whether the interrupt service routine used with RS
is downloaded.
Refer to AH500 Programming Manual, and check the
instruction FWD.
Refer to AH500 Programming Manual, and check the
instruction REV.
Refer to AH500 Programming Manual, and check the
instruction STOP.
Refer to AH500 Programming Manual, and check the
instruction RSDT.
Refer to AH500 Programming Manual, and check the
instruction RSTEF.
Download I/O interrupt service routine 0-31
(I/O interrupt 0-31).
Download I/O interrupt service routine 40-251
(I/O interrupt 40-251).
Check whether the action in the sequential function chart
is assigned qualifiers related to time.
Check whether the reset modifier assigned to the action
in the sequential function chart conflicts with another
modifier assigned to the action in the sequential function
chart.
Check the program, compile the program again, and
download the program again.
Check the Ethernet cable securely connected and is
functioning normally.
1. Check the program and the related special data
registers.
2. Set the Ethernet parameter for the CPU module in
HWCONFIG again.
