10.4.4 Controller number (serial number)
The controller number is individually assigned to each
device and can be used to uniquely identify the
RESISTRON temperature controller in a CAN network.
It is divided into two parts, in order to comply with the
message format (
section 10.2 "CAN protocol" on
page 26). Each part consists of three digits, which are
stored in BCD format in "value.H" and "value.L".
10.5
Temperature meter (actual value
output)
The RES-409 supplies an analog 0…10VDC signal,
which is proportional to the real ACTUAL temperature,
at terminals 17+18.
Voltage values:
0VDC
0°C
10VDC
300°C or 500°C
(depending on controller configuration)
The relationship between the change in the output
voltage and the ACTUAL temperature is linear.
Only the 300°C and 500°C temperature ranges appear
at this actual value output. If a temperature range of
200°C is set with CAN message address 8 ("Alloy/
range"), it appears at this output in the 0…300°C
range. A 400°C temperature range is indicated as
0…500°C.
An indicating instrument can be connected to the
output in order to visualize the temperature of the
heatsealing band.
The characteristics of the ROPEX ATR-x temperature
meter (size, scaling, dynamic response) are ideally
suited to this application and this instrument should
