Special features in program execution

●

You create the user program for the S7-1500R/H redundant system in the top CPU (for

example PLC_1) in the STEP 7 project tree.

●

The S7-1500R/H redundant system does not support some of the instructions the

S7-1500 CPUs. Instructions that are not supported by the S7-1500R/H redundant system

are grayed out in STEP 7 in the "Instructions" task card.

STEP 7 shows the instructions that are not supported in the program code in red. If you

compile program code with instructions that are not supported, STEP 7 outputs an error

message.

The instructions that are not supported are set out in the section Restrictions (Page 150).

●

In the case of instructions with the "LADDR" block parameter, you use this parameter to

determine which of the two CPUs is the target of this instruction.

Example: To read out the I&M data of the CPU with redundancy ID 1, specify the HW

identifier 65149 (or the "Local1" system constant) at the "LADDR" block parameter of the

Get_IM_Data instruction.

You can find more information about the block parameters and the system constants of

the S7-1500R/H redundant system in the STEP 7 online help.

●

In the case of a SYNCUP, the execution time of many instructions operating

asynchronously is extended.

●

Temporary local data for functions (FCs): The system initialization for standard access is

identical for S7-1500R/H-CPUs as for optimized block access. Information on system

initialization for optimized block access can be found in the STEP 7 online help.

Programming style guide

The programming guidelines described in the programming style guide help you to create a

uniform program code that is easier to maintain and reuse. This means that errors can be

detected (e.g. by compiler) and avoided early on.
The programming style guide is available on the Internet
