A transparent and unique diagnostic concept forms the basis of all function blocks. Thus, it is
ensured, that, regardless of the supplier's implementation, uniform diagnostic information is
available to the user in the form of DiagCode. If no error is present, the internal status of the
function block (state machine) is indicated. An error is indicated via a binary output (error).
Detailed information about internal or external function block errors can be obtained via Dia-
gCode. The function block must be reset via the different reset inputs.
Suppliers may add additional interfaces via function blocks with supplier-specific diagnostic
information.

Description
The FB is not activated or safety CPU is halted.
bin
Shows that the activated FB is in an operational state without an error.
X = FB-specific code.
Shows that the activated FB is in an error state.
X = FB-specific code.
Description
X = system or device-specific message. This information contains the diag-
nostic information for the system or device, and is mapped directly to the
DiagCode output. (Note: 0000
Description
The FB is not activated. This code represents the Idle state.

For a generic example, the I/O setting could be:
Activate = FALSE
S_In = FALSE or TRUE
Ready = FALSE
Error = FALSE
S_Out = FALSE
Value 16#7FFF at DiagCode output of PLCopen Safety function blocks indi-
cates an internal error.

Note:
This is a manufacturer-specific value defined by AC500-S safety PLC.
The FB is activated without an error or any other condition that sets the
bin
safety output to FALSE. This is the default operational state where the
S_Out safety output = TRUE in normal operation. For a generic example,
the I/O setting could be:
Activate = TRUE
S_In = TRUE
Ready = TRUE
Error = FALSE
S_Out = TRUE
