easy communication modules make it possible for the easyE4 base device to com-
municate with other devices, including devices from other manufacturers. This com-
munication can be through a standard bus system such as Modbus RTU, as well as
through SmartWire-DT. The device has its own firmware and no configurations are
stored on it even though these configurations can be read with the easy com-
munication module. Instead, configurations are forwarded to the easyE4 base device
and stored there.
EASY-COM-... easy communication modules can be used with an easyE4 base device
starting with generation 05.
(ID on the nameplate, → page 35)
It may be necessary to update the firmware on the easyE4 base device
before use.
Only one of the easy communication modules is supported per easyE4
base device.
The easy communication modules need to be connected to the left side of the
easyE4, while an I/O expansion for easyE4 control relays is connected to the right
side.
The easy communication modules for easyE4 control relays are configured in
easySoft 8. You can find the device catalog in the Communication modules folder.
For assignment purposes, easy communication modules are numbered, with the cor-
responding ID starting with the letter "C". If modules are added later on to a com-
munication module, they will be numbered accordingly (e.g., C1.1, C1.2, C1.3).
The following easy communication modules are available:
l
EASY-COM-SWD-C1 as a SmartWire-DT coordinator
Only available on firmware version 1.30 or higher.
By using an EASY-COM-SWD-... communication module, you can have the
easyE4 function as a SmartWire-DT coordinator that coordinates the SmartWire-
DT line with all the modules on the line and manages the data transmission pro-
cess. This communication module is hereafter referred to as SmartWire-DT
coordinator.
l
EASY-COM-RTU-M1 to Modbus RTU communications
Only available on firmware version 1.40 or higher.
The communication module can be configured as a Modbus RTU master or as a
Modbus RTU slave.
