MCS-PLANT MANAGERChapter - 1.REVISION 1.4Introduction to CPM (Chiller Plant Manager)This software is designed to control a site that consists of multiple chiller packages that are being controlled by individualMCS MAGNUMS.Each MCS MAGNUM controls its own chiller package and sends the CPM information as to its state.The Chiller Plant Manger will control the process pumps to ensure that the required water flow is maintained and thenstage the chiller packages to meeting the cooling requirements of the site. The Chiller Plant Manager is based upon theCPM V17 and Chiller HVAC V17 software family.The Chiller Plant Manager will maintain water flow by controlling the pumps. To determine the site needs, the ChillerPlant Manager will compare the control temperature to the temperature target and develop the step capacity needed.The Chiller Plant Manager can also review an input signal that limits its loading capacity. This is used for load limiting.Communications between the Chiller Plant Manager and the MCS-MAGNUMS on the chiller packages is accomplishedover the RS485 network. Messages are transmitted to the MCS-MAGNUMS that indicate if that package can run andthe maximum number of steps if fixed step system or maxi
