Setting Teamwork Parameters

Procedure

1. On the home screen, tap > Teamwork Settings, to enter the Teamwork Settings page.

2. Set teamwork parameters.

   All teamwork control parameters can be set on the master smart cooling product. Only Teamwork group No., System address, Enable teamwork CAN resistor, Teamwork function and Networking mode can be set on slave smart cooling products. Other parameters of the slave units will be modified by the master unit synchronously. Table 4-7 describes how to set the parameters.

   Table 4-7 Teamwork settings

   Parameter	Description	Configuration Principle	Default Value
   Teamwork group No.	The number of the teamwork group. This parameter should be the same for all units in the same teamwork group.	Set the assigned teamwork group number.	1
   System address	The addresses of units in the same teamwork group cannot be the same.	Set the assigned unit address.	NA
   Enable teamwork CAN resistor	Indicates the build-out resistor status of each smart cooling product in a teamwork group. Set the parameter if CAN network is used.	Set this parameter to No for non-teamwork scenarios. For teamwork scenarios, set this parameter to Yes for the first and last smart cooling products in a teamwork group, and set it to No for other smart cooling products.	No
   Teamwork function	Indicates whether to disable or enable the teamwork function. If the function is disabled, a unit operates independently. If the function is enabled, a unit operates in a team with other units.	Set this parameter based on the onsite device heat distribution.	Disable
   Networking mode	Specifies the networking mode for teamwork control. The networking mode set on the screen must be consistent with the actual networking mode. Otherwise, the teamwork control function will be unavailable. If the networking mode changes, select the corresponding networking mode on the screen. If the networking mode is changed on the screen, the software will restart and the system will run in the new networking mode. (If the software version is V200R002, the system does not need to be restarted after the networking mode is changed.)	Use the CAN or MAC_CAN networking mode. CAN network indicates teamwork control over a CAN bus. MAC_CAN network indicates teamwork control over an FE port.	MAC_CAN network (for V200R001 version) CAN network (for V200R002 version)
   Number of systems in this group	Specifies the number of smart cooling products in a group. The value is an integer ranging from 1 to 32.	Enter the total number of smart cooling products in the group.	3
   Number of running systems in this group	Set the number of running units in this group. The value is an integer ranging from 1 to the value of Number of systems in this group.	The master unit assigns running units in ascending order of the addresses. The address should be in the range of 1–32. The remaining units are automatically classified as standby devices.	2
   Rotation function	Indicates whether to allow the smart cooling products to work as the standby device in turn, maximizing their service life.	It is recommended that the function be enabled when the load is even.	Disable
   Rotation period	Rotation days (1–30).	7 by default	7 day (s)
   Rotation time	24 hours in a day (0–23).	0 by default	0
   Forced rotation	Specifies whether to enable forced rotation regardless of the specified rotation time. After a forced rotation, the rotation period starts again.	This item is set to No by default. If forced rotation is required, the function is set to Yes.	No
   Requirement control	Specifies whether to enable or disable the requirement control function on the master unit. When Requirement control is set to Disable, the master unit does not synchronize operating data to slave units, and all the smart cooling products in the group operate based on their own requirements, not referring to the mode delivered by the master unit. When Requirement control is set to Anti-competitive running, the master unit synchronizes operating data (the temperature and humidity control type and set points of the master unit) to the slave units, and all the smart cooling products in the group refer to the mode delivered by the master unit. When this parameter is set to Indoor fan unified control or Central load distribution, all smart cooling product fans in the group rotate at the same speed.	Anti-competitive running is recommended for the following scenario: In one teamwork group, the temperature and humidity control type and temperature and humidity set points of units are the same, and device heat loads are distributed evenly.	Disable
   Cascade function	When requirement control is enabled, you can enable the cascade function to start standby units if running units cannot meet the cooling capacity requirement.	If the heat load to the device increases, the cascade function is recommended.	Disable
   Differential pressure sharing (This parameter is shown in V200R002 and above versions)	When this parameter is enabled, the smart cooling product, which is not configured with the differential pressure sensor in the group, is logically controlled by using the acquired value of the configured differential pressure sensor.	This parameter can be enabled when there are at least two smart cooling products in the group are configured with differential pressure sensors.	Disable
   Cold aisle temperature and humidity sharing (This parameter is shown in V200R002 and above versions)	This parameter can be enabled only when at least two smart cooling products in the group are equipped with cold aisle T/H sensors. When this parameter is enabled, the smart cooling product, which is not equipped with the cold aisle T/H sensor in the group, is logically controlled by using the acquired value of the cold aisle T/H sensor.	This parameter can be enabled when there are at least two smart cooling products in the group are configured with cold aisle T/H sensors.	Disable
   Hot aisle temperature and humidity sharing (This parameter is shown in V200R002 and above versions)	This parameter can be enabled only when at least two smart cooling products in the group are equipped with hot aisle T/H sensors. When this parameter is enabled, the smart cooling product, which is not equipped with the hot aisle T/H sensor in the group, is logically controlled by using the acquired value of the hot aisle T/H sensor.	This parameter can be enabled when there are at least two smart cooling products in the group are configured with hot aisle T/H sensors.	Disable

3. Complete the teamwork settings for all the smart cooling products by performing 1 and 2.
4. On the home screen of any teamwork controlled smart cooling product, tap . If the teamwork control succeeds, the teamwork topology of the smart cooling product in the group is displayed, as shown in Figure 4-9. Table 4-8 describes the note for the screen.
   Figure 4-9 Teamwork topology
   
   Table 4-8 Notes for the screen

   No.	Item	Note
   1	On/Off	On indicates that the smart cooling product is started and Off indicates that the smart cooling product is shut down.
   2	01, 02, 03	Indicates the device address. The minimum address is the master one and the rest are all slave ones. NOTE: If the master one is offline, the online device with the smallest address is selected to be the new master.
   3	Active/Standby	Active: An active unit properly responds to control requirements. Standby: A standby unit responds to control requirements only if an active unit is faulty (critical alarm, shutdown, or offline) or the active unit cannot meet cooling requirements.
   4	M/S	M indicates the master unit, and S indicates a slave unit. A blue icon indicates that the unit is operating, and a gray icon indicates that the unit is idle.
   5	Frame: green/non-green	A green frame indicates the unit itself, as shown in .
   		A non-green frame indicates other units in the group, as shown in .
   6	Ground color: red, bright gray	Red indicates that a critical alarm is generated, as shown in .
   		Bright gray indicates that the device is operating without any critical alarms, as shown in .

   If teamwork succeeds, the teamwork icon is green. If teamwork fails, the teamwork icon is red. If teamwork mode is disabled, the teamwork icon is gray.
