Error
Code
Description Solution
16#E206
The model number for the control mode
CPU and the standby mode CPU are not
the same.
Use two same models and assign one as the
control mode CPU and the other as the standby
mode CPU.
16#E207
The firmware version for the control mode
CPU and the standby mode CPU are not
the same.
Use two same models and assign one as the
control mode CPU and the other as the standby
mode CPU.
16#E208
Ethernet for the control mode CPU and the
standby mode CPU are not in the same
physical network.
The IP address and mask for the control mode
CPU and the standby mode CPU must be on the
same physical network.
16#E209
The I/O configurations of the control mode
CPU is not the same as the actual I/O
configurations of the standby mode CPU.
(while checking the validation)
Make sure the IO configurations on the
backplane for the control mode CPU and the
standby mode CPU are the same. Both the
control mode CPU and the standby mode CPU
must be connected to the backplane. And make
sure the firmware versions for the control mode
CPU and the standby mode CPU are the same.
16#E20A
The I/O configurations of the control mode
CPU is not the same as the actual I/O
configurations of the standby mode CPU.
(after the validation is checked)
Make sure the IO configurations on the
backplane for the control mode CPU and the
standby mode CPU are the same. Both the
control mode CPU and the standby mode CPU
must be connected to the backplane. And make
sure the firmware versions for the control mode
CPU and the standby mode CPU are the same.
16#E20B
System error
Check the error log for more information
16#E20C Synchronization error
While downloading, the system can not
synchronize. Try again later.
16#E20D
Validation failed
Check the standby mode CPU error log
16#E20E
I/O bus fault
Clear the I/O bus error
16#E20F
Heart beat error
Check the standby mode CPU error log
16#E210
Heart beat communication timeout
Make sure the fiber module is well-connected.
16#E211 Synchronization failed
Power off and then power on the standby mode
CPU and start synchronization again. If the error
still occurs, contact the local authorized
distributors.
16#E212
The standby mode CPU is being switched.
Try again later.
16#E213
There is no program on the PLC.
Check the error log for more information
16#E214
PLC program is damage.
Check the error log for more information
16#E215
Scan time out
Check the error log for more information
16#E216
CPU access denied
Check the error log for more information
16#E217
System busy (RST)
Try again later.
16#E218
System busy (CLR)
Try again later.
16#E219
Turning on the system
Wait
16#E21A
Initialization error
Resupply power and turn it on again.
16#E21B
CPU parameters are damage.
Check the error log for more information
16#E21C
Non-latched area error
Check the error log for more information
16#E21D
CPU EIP parameters are damage.
Check the error log for more information
16#E21E The I/O configuration file does not exist.
Download a correct I/O parameter file via
HWCONFIG again.
16#E21F The I/O configuration file is damage.
Download a correct I/O parameter file via
HWCONFIG again.
16#E221
PLC program error
