DESCRIPTION
PROCESS IMAGE
System status and I/O status are available on the cyclic process image, while I/O diagnostics, system errors and
the UG 6911 program CRC are accessible as acyclic data.
The process image has a fixed size with subsections for each information group: there are sections showing the
status of the SAFEMASTER PRO -inputs, the status of the safety outputs, the status of the probes and, if the
dedicated module is present, the value of the analogue measures.
The Fieldbus inputs allows the PLC to cyclically send up to 32 ON/OFF status and are
used as unsafe inputs in the SAFEMASTER PRO programm.
The system status bits are described as follows
The system status is displayd in a byte
- Bit 0 present SAFEMASTER PRO presence.
- Bit 1 present diagnostic presence.
- Bit 2 error presence.
This byte is always present
The acyclic sections for diagnostics or errors report significant data if the relative bit is present in the status byte.
The section dedicated to the input status has a size of 16 bytes and allows to know the status of up to 128 inputs.
The priority order of the modules is as follows:
• UG 6911.10 / UG 6911.12/080, UG 6916.10, UG 6913.16, UG 6913.08, UG 6913.12, UG 6917, UG 6916.12/080.
The section dedicated to the safety outputs status has a size of 4 bytes and allows to
know the status of up to 32 outputs.
The priority order of the modules is as follows:
• UG 6911.10/ UG 6911.12/080, UG 6916.10, UG 6912.02, UG 6912.04, UG 6914.04/000, UG 6914.04/008,
UG 6912.04/100, UG 6916.12/080.
If two or more modules of the same type are installed the one with the lowest node number is shown first.
Each module with inputs has a number of bits corresponding to the number of physical
inputs; thus modules UG 6911.10/ UG 6911.12/080, UG 6913.08, UG 6916.10 and UG 6916.12/080 will use 1
byte and modules; UG 6913.08 and UG 6913.16 2 Bytes. The modules UG 6917 uses 1 byte each.
The status of the probe is represented with 4 bytes.
In fieldbus where the allocation is important (e.g. PROFIBUS, PROFINET), the Fieldbus input bytes must be
mapped before the bytes in output.
IIf there is a fieldbus module in the SAFEMASTER PRO -System, SAFEMASTER PRO Designer will include in
the report a table with the I/O index for all inputs, fieldbus inputs, probes and safety outputs in the circuit diagram.
For the process data mapping description for your fieldbus please refer the "Appendix".
- The UG695_ communication module gives access to various information related to the SAFEMASTER PRO
System and allows to send commands from the PLC..
- Each device connected to the SAFEMASTER PRO inputs is characterized by an ON/OFF status and a possible
diagnostic. The processing of the inputs according to the program loaded on the SAFEMASTER PRO generates
the ON/OFF status of the safety outputs which can also have diagnostics.
