1. ESA El mm l 7 y I FE MEC0027R1 Figure 1 2 Commanding Over A Network When an operator issues a command over the BLN network through an MEG that MEC validates the command determines where to send it and then passes the command to the destination over the network For example in Figure 1 2 a command issued by the operator at the MEC located in the lower level of the building is sent by means of the communication network to the field panel located on the penthouse for the purpose of controlling the main air handling unit of the building FLN The communications link that passes information between an FLN device or devices and a Building Level Network BLN device NOTE Only MEC Models 200F 210F and 300F 310F provide FLN communication ports Other MEC products do not For more information about networking contact your local Siemens Building Technologies representative Siemens Building Technologies Inc 1 5 Modular Equipment Controller Owner s Manual MEC Remote Sites 1 6 One MEG can act as a stand alone field panel The field panel is generally used in remote sites where only one field panel is needed to control the equipment for that site A remote site may also include a local BLN of up to 100 MECs or other P2 controllers Communications with the remote site are achieved through the use of dial up modems and APOGEE Ethernet Microservers AEM AEM100

3. 1 2 The MEC continuously executes a user defined set of instructions called the control program This program uses the most recent point values and the most recent clock time The control program does the following e Evaluates control strategies e Uses an internal calendar and time clock for time based functions e Updates point values and commands field points according to the program results e Sends messages or reports to proper terminal locations as needed For example during the day a fan turns ON if the room temperature rises above 80 F 27 C and turns OFF when the temperature drops below 73 F 23 C Between 5 00 P M and 7 00 A M the fan is turned OFF regardless of the room temperature If the temperature rises to 85 F 29 C at any time the MEC sends an alarm message to an alarm printer These specifications can be met by 1 Connecting a room temperature sensor transmitter and fan starter to the MEC 2 Defining the room temperature sensor with a high alarm limit of 85 F 29 C and the fan points in the MEC database 3 Writing a short control program that defines your control strategy 4 Enabling the execution for that portion of the control program Siemens Building Technologies Inc Introduction To perform this control strategy the MEC continuously executes the control program It samples a current or voltage signal representing the room temperature and updates the value associated with that temperature
