4.16.4.10.9 HIPERFACE
4.16.4.10.9.1 HIPERFACE - Digital interface configuration
HIPERFACE builds upon the RS-485 (EIA-485) specification and permits communication with multiple HIPER-
FACE slaves.
There are two methods available to use the slave data in a PLC program. One is to store the necessary slave
values temporarily in the module, where they can then be provided to the CPU. The other is to use the module's
FlatStream mode, which supports the full range of commands defined in the HIPERFACE specification.
Additional information regarding the HIPERFACE specification is provided in the "Description of HIPERFACE"
document.
HfMode
Names (pChannelName):
HfMode
This register is used to enable the HIPERFACE interface and must always be set to the value 1 for configuration
reasons.
Data type
Value
USINT
1!
Bus controller default: 1
HfParity
Names (pChannelName):
HfParity
This register configures the parity bit for the interface.
Data type
Value
USINT
69 ... E → Even parity
78 ... N → No parity
79 ... O → Odd parity
Bus controller default: 69
HfCharTimeout
Names (pChannelName):
HfCharTimeout
This register configures the time that the module waits after receiving the last data block to add additional data to
the current data packet (frame). When this time expires, the data received thus far is saved in a frame. The transfer
is complete and the data can be evaluated.
Information:
Time is specified as a char value in order to ensure identical behavior regardless of the baud rate
setting.
Data type
Value
USINT
1 to 255 [char]
Bus controller default: 55
