Connecting the Teamwork Network Cable
Smart cooling products in a teamwork group must be of the same model.
CAN Teamwork Networking (CAN Protocol)
A maximum of 32 smart cooling products can be teamworked. If CAN networking is required onsite, set Teamwork CAN resistor enable on Teamwork Settings of the first and last smart cooling products to Yes.
- Prepare an 8-pin standard network cable. The following figure shows the wire sequence requirements.Figure 3-52 Pin sequence of the CAN_IN/CAN_OUT network cable
- Connect the CAN_OUT port of each smart cooling product to the CAN_IN port of the following smart cooling product using a CAN network cable, as shown in Figure 3-53.
- Secure the cables.
Connecting Monitoring Network Cables
Northbound RS485 Monitoring (Modbus-RTU Protocol)
When the host monitors smart cooling products over northbound RS485 ports, it takes 3 seconds to collect all data of a single smart cooling product. Therefore, the time required for collecting data from N smart cooling products in a group is 3 x N seconds. If the time required for the host to collect data of all smart cooling products does not meet performance requirements, the smart cooling products can be grouped for data collection. For example, if the host needs to collect data of all smart cooling products within 12 seconds, it is recommended that every four smart cooling products be divided into one group. Connect the COM port on the main control module of the last smart cooling product in each group to the RS485 port on the host.
- Prepare the COM network cable by referring to Figure 3-54.
Cut the wires for pins except pins 4 and 5 to prevent introducing interference signals.
- Connect the monitoring cables by determining whether there is the teamwork control function.
- If there is no teamwork control, connect the COM/FE port on each smart cooling product to the customer's monitoring system. After the smart cooling products are powered on, set RS485 monitoring grouping to Enable for each smart cooling product. Path:
- In CAN networking without grouping, connect the COM/FE port on the last smart cooling product to the monitoring device, as shown in Figure 3-55. After the smart cooling products are powered on, set RS485 monitoring grouping to Enable for the last smart cooling product. Path:
- In CAN networking with grouping, connect the COM/FE port on the last smart cooling product in each monitoring group to the monitoring device, as shown in Figure 3-56. After the smart cooling products are powered on, set RS485 monitoring grouping to Enable in each monitoring group. Path:
FE Monitoring (SNMP/Modbus-TCP Protocol)
- Connect one end of a monitoring network cable (standard network cable) to the FE_1 or FE_2 port on the main control module of a smart cooling product, and connect the other end to the monitoring device.Figure 3-57 Connecting the FE monitoring network cable
This scenario is applicable to the scenario where a network management system is connected, regardless of the networking.
