Enhanced Communication Module (ECM)
The Enhanced Communication Module (ECM) provides communications
over a four-session Ethernet port and a Universal Serial Bus (USB) 2.0
port. See
Figure 5-6
. The FB107 supports up to two ECM modules
installed in slot 1 and 2 of the FB107 base unit
Note:
When you install a communication module in slot 2 on the base
unit, the system redirects the communication port (COM2) on the
CPU to the type of module in slot 2.
Caution
Disable sleep mode when using the Enhanced Communications module.
Also, set clock
speed to 14 MHz or higher. Use the CPU module’s
Advanced tab to set both these values.
The FB107 supports the Modbus master/slave (ASCII or RTU) and
Modbus TCP communications protocols. Use ROCLINK 800
Configuration software to configure the module.
Each communication module uses a separate channel from the other
modules and has a common (“single-ended”) ground. The field interface
protects the electronics in the module. Filtering reduces the effect of noise
on communication errors.
