External specification of a speed

If the actual belt speed is available externally (e.g. in a CPU), you can send this to the scale
using data record 19 (→ Scale parameters and functions of the belt scale (Page 69)). To do
this, set the speed detection to "Speed from CPU (DS19)" in the "Basic parameters 2 of 2" in
menu item 1.1.2. The "Nominal belt speed" is then only used as a reference for the speed
limits.
As soon as data record 19 is sent with a content not equal to 0 to the electronics (from
SIMATIC CPU or with Modbus TCP / RTU), this value is used as the current speed. The "Set
"Belt is running"" and "Reset "Belt is running"" commands are not required. In order to stop
the belt, write a value of 0 into data record 19 and send this to the electronics.
Following a power loss, a value of 0 is used automatically, and you must again send the
current speed externally.
