Step 2 When the EMS monitors smart cooling products over RS485, the time needed for collecting
all data from a single smart cooling product is 3 seconds. In the teamwork mode of cascading
using an RS485 bus for monitoring, it takes the host 3 x N seconds to collect data from N
smart cooling products in the group. If the EMS needs more time to collect data from all
smart cooling products than what the EMS performance requires, the smart cooling products
can be grouped for data collection. Assuming that the EMS needs to collect the data from all
smart cooling products within 12 seconds, you are advised to incorporate four smart cooling
products in one group and connect the COM port shown by (7) in
smart cooling product for each group to an RS485 port on the EMS.
32 teamworked smart cooling products, four in each group, connect to the EMS.
