Bytes 4...62: Module-specific diagnostic data: General coding
This byte contains data with module-specific information that is described in the respective
module documentation. The particular module is identified by the slot (byte 2).
Bytes 4...62: Module-specific diagnostics for "Status type" and "Modul_Status"
In the case of the "Status type" variant of device-specific diagnostics from DP V1 slaves (see
byte 1, bit 7) and the "Module_Status" setting (see byte 1, bits 0...6) two status bits are
provided here for each slot (= module). Unneeded bits are set to 0.
