5.3 Parameter data
More precise information regarding the system status can also be retrieved using the acyclical communica-
tion channel.
All of the settings (e.g. control thresholds, switching points, permitted leakage, and so on) for the SCTMi
can also be read or modified. You can access additional identifying information for the SCTMi, such as
part number and serial number, and save user-specific information such as the installation or storage loca-
tion.
The precise meanings of the data and functions are further explained in the section “Functions of the
Compact Terminal and the Ejectors.”
For the PROFINET and EtherCAT communication protocols, the following start addresses apply for the pa-
rameter data:
SCTMi Variant Start Address
PROFINET 0x0000
EtherCAT 0x2000
Ethernet/IP See below
Parameters marked with the addition [ part of processdata ] are also automatically included in the cyclical
exchange of process data.
To access the parameter data via Ethernet/IP, an object (also known as a class), an instance and an at-
tribute must be specified in the object-based “Common Industrial Protocol” (CIP).
The 0xA2 object can be used to read—and write, depending on access rights—all parameter data with the
following services:
• 0x0E: Get_Attribute_Single
• 0x10: Set_Attribute_Single
The instance corresponds to the offset from the parameter data table.
The following attributes are available:
# Name Access Type Description
1 Name Get SHORT_STRING Parameter name
2 Data type Get Array of USINT BOOL (0), SINT8 (1), SINT16 (2), SINT32 (3),
UINT8 (4), UINT16 (5), UINT32 (6), CHAR (7),
ENUM (8), BITS8 (9), BITS16 (10), BITS32 (11),
OCTET (12)
3 Number of ele-
ments Get USINT Number of elements of the specified data
type
4 Access rights of
the instance Get Array of USINT Specifies the access rights for the instance:
Bit 0: 1=read rights
Bit 1: 1=write rights
