The "FSCP Test Mode" is mentioned several times in the PROFIsafe specification, but it is not defined explicitly.

This is true as for now. The FSCP Test Mode is only defined by describing its behavior in certain circumstances. This issue has been noted and will be addressed in a future version of the specification.

Here is a definition:

The FSCP Test Mode can be used for commissioning of a device where the iParameters are not yet fully defined and need further testing in the plant. With this test mode it is allowed that the F-Driver is running and the F-Device is allowed to perform cyclic PROFIsafe communication with the F-Host. If the FSCP Test Mode is supported by a device, it needs to be described in the device's manual.

When in FSCP test mode (there is cyclic PROFIsafe communication, and F_iPar_CRC is set to 0x00000000) - is the F-Device expected to send diagnostic message 0x4b (75), "Inconsistent iParameters (iParCRC error)"? (in addition to an indication using LED or HMI)
