Configuring of global measuring inputs on the D410 
Global measuring inputs can be freely assigned to the axes (drives) and add an internal 
timestamp to the measurement result for more precise determination of the axis positions. 
The drive and the probe input do not need to be located on the same control unit. The 
measuring results are not transferred using the axis message frame, but using the 391/392 
axis message frame.

DI/DO 9, 
DI/DO 10 or 
DI/DO 11 
In addition to the settings of the parameters, message frame 391 (max. two measuring 
inputs) or message frame 392 (max. three measuring inputs) must be set for the control unit. 
The p680 parameter is used to define a terminal as global probe inputs. Message frame 391 
can be used to assign the p680[0..1] parameter; message frame 392 can be used to assign 
the p680[0..2] parameter. The parameter used to set the required terminal is not relevant. 
The assignment of the measuring input to an axis is made using the logical hardware 
address and the bit number of the digital input to be used as measuring input (see also 
Section Use of message frame 39x (Page 87)). 
The p490 parameter of the control unit can be used to invert a measuring input. 
 
 
Note 
The p684, and r685 to r688 parameters of the control unit have no relevance for SIMOTION.
 
 
Note 
When the 39x message frames are used, a HW Config must always be performed after 
changes have been made to onboard I/O-relevant parameters. "Download to the target 
system" must then be used to download the changed configuration data into the target 
device.
