6.2.Module Specifications
Number of Channels: 30 ch/module
No. of messages (ID): 30
Sampling interval: 10 ms–60 s
Max. no. of installed modules: Differs by slot width setting (no. of ch used per module)
Slot Width Setting Max. No. of Ch Used Max. no. of Modules (per System)
1 10 ch 6
2 20 ch 5
3 30 ch 4
Multi-interval: Allowed. However, if the slot width is 2 or 3, a separate measurement interval cannot be set
for the real and virtual instances of the same module.
Mode switching: Switch between Setting and Measurement modes with hardware dip switch.
Setting mode: CAN bus settings can be entered externally from a PC using a SERIAL (connector).
Measurement mode: CAN bus data can be captured and transferred to the MW100 using a CAN
(connector).
Data range: -30000–30000 (range of data that can be transferred to the MW100)
Set using the upper/lower limit of span.
Scaling computation: The following scaling computation is carried out inside the module.
