Static And Dynamic Data Transmission - Bosch Rexroth ID 40 Manual

Fig. 7: Alignment of ID 40/MDT for lateral reading and writing
The read/write distances are listed in the following table in relation to the states and
alignment, and are valid to the following limits:
• Max. height difference of ±5 mm between MDT and SLK.
• Max. lateral difference of ±10 mm between centerlines of MDT and SLK

With frontal alignment and a nominal distance of 4 mm, dynamic reading and writing
is possible over a 40 mm section.

Static and dynamic data transmission

Data can be transmitted between the MDT and the SLK both statically and
dynamically. In static mode, the MDT comes to a stop directly in front of the SLK. In
this instance, the dwell time can be as long as desired, i.e., data can be exchanged
for an unlimited amount of time. However, the MDT must remain in range until
communication is complete.
In dynamic mode, the MDT moves past the SLK during communication. In this
instance, the dwell time in the field is determined by the transport speed. The data
quantity being transferred has to be adjusted to the dwell time by programming the
user controller.
The MDT can approach and pass the SLK in different directions:
• Horizontally, as shown in Fig. 6. This is the optimal mode.
• Vertically. Here the dwell time in transit is limited.
ID 80/E-MDTs can experience sporadic communication errors, which is why this
direction is only recommended for ID 40/MDTs.
• Frontally. The MDT approaches the SLK from the front and must be stopped within
the specified distance range.
