Procedure for Modifying Hardware and Application Program¶

In order to modify hardware configuration or application program while HA-CS31 system is running, proceed as follows:

Execute all necessary changes.
Compile the project.
Make sure that there is no error in the program.
We recommend you, to carry out a ‘Clean All’ and ‘Rebuild All’.
Select the communication channel of the primary CPU.
Download the modified program.

⇒

Now the CPU goes to STOP mode and there will be a changeover to secondary CPU.
After a successful download, set the primary CPU to RUN mode and create a boot project.

⇒

Now, the primary CPU is updated with the new program.
Select the communication channel of the second CPU which is now the primary. Download the modified program.

⇒

The CPU switches to STOP mode which results in a change over to the original CPU. The original CPU will start working as Primary.
After a successful download, set the CPU to RUN mode and create a boot project.

⇒

The complete system works in the same status as before modification.

Note

After adding or deleting the HA_CS31_DATA_SYNC function block or any HA-CS31 utility function block, restart the complete system.

Note

It is absolutely necessary that both CPUs have identically user programs.

Note

The replacement of CI590 is possible with a normal HA-CS31 system, which otherwise has no error: PLC A has to be the primary.

For replacement of CI590 when PLC B is the primary, the following pins of TU522-CS31 must be bridged before:
