4.3. Connection example
Hint: In order to avoid undefined input states and unwanted or wrong switching processes, we
suggest to connect the device’s switching outputs after You have configured the device
properly.
4.3.1. Connection information:
The interface-converter can supply the specifieded numbers of EASYBUS standard loads (max. 30 pieces).
The module management is limited to max. 20 EASY
BUS-measuring channels.
Please note that some EASY
BUS -modules have a higher bus load as the standard load!
Please notice the corresponding specification in the module manual.
Bus loads of some EASY
BUS modules:
EASY
LOG-family: 2 EASYBUS standard loads
EBN: 2 EASY
BUS standard loads
EBHT, EBT, EBH: 1.5 EASY
BUS standard loads
GIA20EB, GIR2002: 1 EASY
BUS standard load
W hen connecting the modules keep in mind that the sum of all bus loads of the modules must not exceed
the maximal allowed number.
Worked sample:
1) Connection of 5 EASYLOG, 8 EBHT and 7 GIA20EB:
5 * 2 + 8 * 1.5 + 7 * 1 = 10 + 12 + 7 = 29 standard loads (20 devices) => connection is possible
2) Connection of 15 EASY
LOG and 2 EBN:
15 * 2 + 2 * 2 = 30 + 4 = 34 standard loads (17 devices) => EB3000 are overloaded!
3) Connection of 4 EBHT and 20 GIA20EB:
4 * 1.5 + 20 * 1 = 6 + 20 = 26 standard loads (24 devices / 28 meas. channels) => max. number of meas. channels transcended!
Please note: The EASY BUS -modules can feature more as one measurement channels (e.g: EBHT, ...)
