GE IC687BEM731｜Expansion Bus Module｜

Core technical parameters
Communication specifications
Bus type: Dual independent Genius Bus master station, channels CH1 and CH2 are isolated from each other, completely independent of two networks
Baud rate: Genius bus fixed 153.6 kbps, non modifiable
Maximum number of nodes per channel: up to 32 Genius nodes per channel; The maximum total number of Genius slave nodes for the entire machine is 64
Bus medium: Dedicated Genius shielded twisted pair cable
Bus distance:
No repeater: maximum 2000m per channel
Use IC670ACC001 Genius repeater, with a maximum of 8 relays per channel and a maximum of 6400m
I/O data capacity:
Maximum 4096 discrete inputs and 4096 discrete outputs for the entire machine
The maximum analog quantity is 512 AI channels+512 AO channels
Supports Genius Global Data, allowing for direct exchange of data between nodes without the need for CPU forwarding
Each channel independently manages the network, and a bus failure does not affect the operation of another channel
Hardware and rack power consumption
Applicable rack: GE Series 90-70 PLC (5-slot/10 slot rack), ordinary I/O slot
Power supply: 90-70 backplane power supply, no external power supply required
Backboard consumption: 5VDC, maximum 1.3A
Interface: 2 × DB-9 female ports, corresponding to CH1 and CH2 Genius buses respectively; On board dip switch setting module parameters
LED status indicator light:
PWR: Module Power Supply
RUN: Module running
OK: Module self-test is normal
BUS1 Fault: Channel 1 bus fault
BUS2 Fault: Channel 2 bus fault
Firmware EPROM, common firmware versions V4.30 and V4.40; Replacement of spare parts requires compatibility between firmware and CPU firmware versions
Diagnostic capability
Dual channel independent fault reporting: wire breakage, short circuit, node loss, and slave station fault are reported separately to the PLC system status register
Fault node bypass function: The fault is isolated from the station, and other nodes in the same channel continue to work
HHP handheld programmer can be used to debug two Genius networks, CH1 and CH2, respectively
The PLC user program can read the online/offline status of each channel and node
Environmental mechanical parameters
Installation: 90-70 rack slots, inside the control cabinet, IP20
Working temperature: 0 ℃~+60 ℃
Storage temperature: -40 ℃~+85 ℃
Humidity: 5-95% RH, no condensation
Certification: UL, CE, CSA
