Compatibility with SIMATIC RF180C

Some of the SIMATIC RF18xC/RF18xCI communication module features are different than
those of the predecessor model SIMATIC RF180C. However, these can be migrated or
replaced taking into account the following differences.
Differences in hardware
The differences in the module hardware are as follows:
● The width of the two modules RF180C and RF18xC/RF18xCI is the same for both with
60 mm. The two modules differ regarding the height, depth and position of the fixing
screws. See the dimension drawings of the two modules.
● The RF18xC communication module has an L-coded M12 connector for power supply
and forwarding. When replacing an RF180C with a M12 7/8" terminal block, for example,
with an RF18xC, you need an adapter from M12 7/8" to M12 L-coded.
Differences in the configuration/parameter assignment
You must take the following differences into account during configuring:
● SIMATIC RF180C
The CM has one module in the hardware configuration for both channels.
● SIMATIC RF18xC
The CM has one module in the hardware configuration for each channel.
The channel differences have an effect on addressing in the "HW_Connect" variable or in the
technology object.
Parameter assignment with the technology object:
● SIMATIC RF180C:
In the "Ident device" parameter, select the module "2x RS422 channel_1" of the RF180C
for both channels. Depending on the channel in which the module is used, you must
adapt the module name accordingly ("_2" for channel 2).
● SIMATIC RF18xC
In the "Ident device" parameter, select the module of the corresponding channel (e.g.
"Reader_1" for "Channel1").
