About How to install the network cable of the master and slave controllers of the energy storage cabinet
A PLC master with a DCM interface connected to one or more PLC or DCM slaves is the most popular type of network. The PLC is the network.
In this chapter we’ll use the following example configuration to create a simple master slave network. WARNING: These examples are for illustration purposes only and are not intended for.
NOTE: Remember that the pinout diagrams are different for the DCMs and the bottom CPU port. Make sure the cables are connected to the proper device.
Normally, you can install the modules in any manner. However, we’d like to keep our examples consistent between the different configurations. Install the equipment in the following order. WARNING: To minimize.
The next step is to set the master station DCM communication parameters. We will use the following settings in our example.

6 FAQs about [How to install the network cable of the master and slave controllers of the energy storage cabinet]
Can I use the master/slave function via the Ethernet network?
It is also possible to use the Master/Slave function via the ethernet network. Operation is identical to the standard mode. Note: It is recommended to activate this option only when necessary and on only one card on the network. Activating the Master option on multiple devices sharing the same network will result in unstable performance.
How do I use a Master/Slave interface?
Note that different models of interfaces can be used together as Master/Slave. Next, connect USB cables to a USB hub or directly to your computer if you have enough USB ports to open all devices at the same time in the lighting control software. Below is an example wiring illustration with 3 interfaces connected as Master/Slave.
How does a master device synchronize a slave interface?
The master device plays the current scene and synchronizes the slave devices. The master forces the slave interfaces to play the same scene and the same step at the same time in unison. The slave interfaces are forced to follow the master timings and triggers and slave interfaces will not act, play or trigger a scene independently.
Can rj71dn91 be used as a master/slave module?
Any dedicated instructions of the RJ71DN91 cannot be used. To prevent data inconsistency, set "Refresh Settings" of module parameter. Any module FBs of the RJ71DN91 cannot be used. This section describes the differences in the DeviceNet master/slave module between the MELSEC-Q series (QJ71DN91) and the MELSEC iQ-R series (RJ71DN91).
What is the maximum distance between two slaves in an AS- Interface?
• In each segment, a galvanically separated AS-Interface power supply must be installed. • Hence, the maximum possible distance between two slaves in an AS-Interface network is 500 m, if the master is positioned accordingly (see picture on the next page).
How do I know if my melsec IQ-r DeviceNet master/slave module is bad?
For the specified torque range, refer to the MELSEC iQ-R DeviceNet Master/Slave Module User's Manual (Startup). When using an extension cable, connect it to the extension cable connector of the base unit securely. Check the connection for looseness. Poor contact may cause malfunction.
