2.2 IEBus Communication Protocol
An overview of the IEBus is as follows.
Communication system: Half-duplex asynchronous communication
Multi-master system
All the units connected to the IEBus can transfer data to the other units.
Broadcast communication function (communication between one unit and multiple units)
Group broadcast communication:
Broadcast communication with group units
General broadcast communication: Broadcast communication with all units.
Three modes with different transfer speeds selectable.
f
X
= 12 MHz
f
X
= 12.58 MHz
Maximum Number of Transfer Bytes
(bytes/frame)
Mode 0
Approx. 3.9 Kbps
Approx. 4.1 Kbps
16
Mode 1
Approx. 17 Kbps
Approx. 18 Kbps
32
Mode 2
Approx. 26 Kbps
Approx. 27 Kbps
128
Access control: CSMA/CD (Carrier Sense Multiple Access with Collision Detection)
The priority order for bus occupancy is as follows.
<1>
Broadcast communication takes precedence over ordinary communication (i. e., communication between one
unit and another).
<2>
The lowest master address has the highest priority.
Communication scale
Number of units:
Cable length:
Load capacity:
MAX. 50
MAX. 150 m (with twisted-pair cable <Resistance: 0.1
/m or less>)
MAX. 8000 pF <between BUS– and BUS+>, f
X
= 12 MHz
MAX. 7100 pF <between BUS– and BUS+>, f
X
= 12.58 MHz
Terminating resistor: 120
