SMC-Flex Datalink Configuration Reference 1/9/2012 SMC-Flex Datalink Configuration Datalinks are supported in the SMC-Flex. A Datalink is mechanism used by most drives to transfer data to and from the controller without using an Explicit Message. The SMC-Flex only supports 16-bit Datalinks, therefore the device can be configured to return up to 8 additional pieces of parameter information . By default the 8 parameters (parame ter# 1, 2, 3, 4, 5, 6, 11, 12) are returned in the I/O message when all 4 output Datalinks are configured. These parameters identif y the following values: Parameter #1 = Voltage Phase A-B Parameter #2 = Voltage Phase B-C Parameter #3 = Voltage Phase C-A Parameter #4 = Current Phase A Parameter #5 = Current Phase B Parameter #6 = Current Phase C Parameter #11 = Power Factor Parameter #12= Motor Thermal Usage (MTU) Keep in mind that the returned paramete rs can be changed by simply changing the values in programme d in parameters #89 through #103. Also, only output Datalinks are configured by default. Input Datalinks can be configured, but have limited functionality when used with the SMC-Flex. The following example uses all 4 Datalinks. The communication interface used is the 20- Comm-D DPI to DeviceNet module.

Datalinks are supported in the SMC-Flex. A Datalink is mechanism used by most drives to
transfer data to and from the controller without using an Explicit Message. The SMC-Flex
only supports 16-bit Datalinks, therefore the device can be configured to return up to 8
additional pieces of parameter information. By default the 8 parameters (parameter# 1, 2,3, 4, 5, 6, 11, 12) are returned in the I/O message when all 4 output Datalinks are
configured. These parameters identify the following values:
Parameter #1 = Voltage Phase A-B
Parameter #2 = Voltage Phase B-C
Parameter #3 = Voltage Phase C-A
Parameter #4 = Current Phase A
Parameter #5 = Current Phase B
Parameter #6 = Current Phase C
Parameter #11 = Power Factor
Parameter #12= Motor Thermal Usage (MTU)
Keep in mind that the returned parameters can be changed by simply changing the values in
programmed in parameters #89 through #103. Also, only output Datalinks are configured by
default. Input Datalinks can be configured, but have limited functionality when used with
the SMC-Flex.
The following example uses all 4 Datalinks. The communication interface used is the 20-
Comm-D DPI to DeviceNet module.
