III-11.7 RM_DMS (strain gauge module (No. 22))
Function RM_DMS reads data from a special strain gauge module of KS98-1 I/O extension with CANopen. Max. 2
strain gauges can be connected to the module. The measured values are available at outputs AI 1 and AI 2.
The two measurements can be influenced via digital command inputs, e.g. zero setting. Monitoring a new command (
positive flank at one of the digital inputs ) is restarted only when the “ready” output is “1”. The module position in the
RM rack is determined by connection of analog input Slotx to the RM2xx node.
a
Important hint:
A special coupler module ( RM201-1 ) must be used for operation of the strain gauge module. This coupler module
cannot be combined with thermocouple modules. Moreover, the limitations as for coupler module RM201 (e.g. max. 4
analog input modules) are applicable.
Digital inputs:
set_t1
Set tare strain gauge channel 1. The actual weight is not stored continuously as tare (packaging weight). The follow-
ing measurements provide the net weight.
res_t1
Reset tare strain gauge channel 1. The tare value is set to 0.
Gross weight= net weight.
zero_1
Zero setting of strain gauge channel 1 measured value. The actual measured value is stored as a zero value in a
non-volatile memory.
set_t2
Set tare strain gauge channel 2. The actual weight is buffered as tare (packaging weight). The following measure-
ments provide net weight.
res_t2
Reset tare strain gauge channel 2. The tare value is set to 0.
Gross weight=net weight.
zero_2
Zero setting of the strain gauge channel 2 measured value. The actual measured value is stored as zero in the
non-volatile memory..
