SSC2 - Switching Signal 2
Switching Signal Channel 2
The process data content "SSC2 - Switching Signal 2" describes a signal bit that is used to
detect a position that is critical for the application. It is part of the cyclic signal transmission. The
signal bit can toggle between "0" and "1" depending on the status of the absolute rotary
encoder or of the application.
The SSC2 process data is functionally redundant to the SSC1 process data. It should be
regarded as an independent supplement to this data.
The following parameters influence the switching characteristics of the SSC2 process data:
•
SSC2 Param. SP1
•
SSC2 Param. SP2
•
SSC2 Config. Logic
•
SSC2 Config. Mode
•
SSC2 Config. Hyst

Status - Count Direction
The "Status - Count Direction" process data content indicates the current direction of rotation of
the shaft. It is transmitted cyclically and you can use the "Config - Rotation Direction" parameter
to adjust the settings for the process data.
The "Status - Count Direction" process data content can distinguish between the "increase"
and "decrease" values depending on the setting and the current direction of rotation.

MDC2 - Auxiliary Measurement
Measurement Data Channel 2 - Auxiliary Measurement
The "MDC2 - Auxiliary Measurement" process data content describes another available mea-
sured value that can be read out from the device.
For the ENA***TL-**IO** product group, this additional measured value is the ambient tempera-
ture of the device. The cyclical transmission of an additional measured value offers significant
added value in condition monitoring applications. The content can be set to "deactivated,"
meaning that the measured value is always 0.
Refer to information on the "Config - Auxiliary Measurement" parameter.

Status - Auxiliary Measurement MCD2
Measurement Data Channel 2 - Auxiliary Measurement
The process data in "Status - Auxiliary Measurement MDC2" indicates which measured value
is transmitted via "MDC2 - Auxiliary Measurement."
The following options are supported:
•
"Deactivated" (0) >> measured value is always 0
•
"Temperature" (1) >> ambient temperature
This information is beneficial when evaluating process data remotely, and the exact device set-
ting for the rotary encoder is not known or if several devices with different settings are used
simultaneously.
For the ENA***TL-**IO** product group, this additional measured value is either disabled or
corresponds to the device's outside temperature.
