Bit Description
MODE_DO2 MODE_DO2 is only valid, if LOAD_DO_PARAM: 0 A 1. The virtual output DO2 can show the
status of the data bit SET_DO2 or comparison results if CTRL_DO2 = 1.
MODE_DO2 defines which function DO2 is to accept:
– 00: The output DO2 shows the status of the control bit SET_DO2. This must be released
with CTRL_DO2 = 1.
– 01: Output DO2 indicates:
Counter status reference value 2
– 10: Output DO2 indicates:
Counter status reference value 2
– 11: Output DO2 indicates:
Counter status = reference value 2
A pulse is generated for indicating equal values. The pulse duration is defined by byte 2
of this process output.
MODE_DO1 MODE_DO1 is only valid, if LOAD_DO_PARAM: “0““1“. The physical output DO1 can
show the status of the data bit SET_DO1 or comparison results if CTRL_DO1 = 1. MODE_-
DO1 defines which function DO1 is to accept:
– 00: The output DO1 shows the status of the control bit SET_DO1. This must be released
with CTRL_DO1 = 1.
– 01: Output DO1 indicates:
Counter status reference value 1
– 10: Output DO1 indicates:
Counter status reference value 1
– 11: Output DO1 indicates:
Counter status = reference value 1
A pulse is generated for indicating equal values. The pulse duration is defined by byte 2
of this process output.
Hysteresis value 0…255)
The reference value 1/2 can be assigned a hysteresis value in order to generate a response
at DO1/DO2 with hysteresis.
This will prevent the excessive on and off switching of DO1/DO2 if the count value fluctu-
ates too quickly around the reference value.
Pulse duration (0…255) unit: ms
The reference value 1/2 can be assigned a hysteresis value in order to generate a response
at DO1/DO2 with hysteresis. This will prevent the excessive on and off switching of DO1/
DO2 if the count value fluctuates too quickly around the reference value.
EXTF_ ACK Error acknowledgment
The error bits must be acknowledged with the control bit EXTF_ACK after the cause of the
fault has been rectified. This control bit must then be reset again. Any new error messages
are not set while the EXTF_ACK control bit is set!
CTRL_ DO2 0: The virtual output DO2 is blocked.
1: The virtual output DO2 is enabled.
SET_ DO2 If CTRL_DO2 = 1 and the virtual output DO2 is set to indicate the value SET_DO2, DO2 can
be set and reset directly with SET_DO2.
DO2 can be set for this function via the process output (MODE_DO2 = 00 and
LOAD_DO_PARAM 0 1).
The output DO2 can also be set before commissioning via the separate parameter data.
The default setting for DO2 is to indicate the status of SET_DO2.The output DOx can also
be set before commissioning via the separate parameter data. The default setting for DO2
is to display the value of SET_DO2.
CTRL_DO1 0: The output DO1 is blocked.
1: The output DO1 is released.
