IP67 MDR for EtherNET/IP
Assembly #105
– Configuration Data
Output Process Data (8 bytes)
Bit
Offset (in
byte)
7 6 5 4 3 2 1 0
00 CC7 CC6 CC5 CC4 CC3 CC2 CC1 CC0
01 FV7 FV6 FV5 FV4 FV3 FV2 FV1 FV0
CCx: Channel (x = Channel number) I/O Configuration
This parameter allows to configure each channel as Digital Input or Digital Outputs
0: Input
1: output
FVx : Fallback value (x = Channel number).
This parameter allows to configure the fallback value for each channel configured as digital output.
0: Set to 0
1: Hold last value (last output value will be maintained)
The fallback output behavior will be applied on digital outputs when:
- When the EtherNET/IP scanner is switched from RUN to PROG mode (Idle mode).
- In the event of power error and of loss of bus communication (released or lost).

MDR Features & Behaviors
MDR Startup
To start the MDR, the following steps need to be followed:
1- Set the speed register on each port
2- Set the desired direction (Clockwise / Counterclockwise) on each port
3- Enable / disable the RAMP function
4- Set the start signal register on each port
5- Check the status register to know the status
Note
Because of switching on the power supply and the start signal at the same time results
in peak currents in exceed of 5A, a time delay of 500ms will apply to avoid any damage
to the MDR.
Note
At the module start up and before the first connection with the PLC, the MDR ports are in
Detection mode in a very short time. Therefore, the MDR should be connected to the port
before powering up the module to ensure proper detection. If the MDR is connected to the
port after the Detection mode is elapsed, no MDR will be detected (MDR TDx = 0).
Moreover, the MDR type detected during the Detection mode will still be considered as
being present if you disconnect the cable after the Detection mode. Therefore, we strongly
recommend to not swap 2 different MDR types without a module power cycle.
