FM148R HollySys Power Module, executes programs and stores data to control industrial automation tasks or manage system control points during input and output operations. The input section collects signals from field devices (such as sensors or switches), while the output section controls pumps, motors, indicator lights, and other equipment in industrial settings. The power supply provides electrical support to the CPU and any connected modules. Communication ports are used to connect the CPU to other industrial equipment. Status indicator lights display the CPU's operating mode, the current status of local I/O, and detected system errors. Instruction system 1. Standard contact instructions: LE normally open contact instruction, representing a normally open contact connected to the input bus, i.e., the start of normally open contact logic operation. LDN normally closed contact instruction, representing a normally closed contact connected to the input bus, i.e., the start of normally closed contact logic operation. A with normally open contact instruction
When the power supply is operating normally, the "DOn+" and "DOn-" terminals are connected; when a power failure occurs, the "DOn+" and "DOn-" terminals are disconnected. In cases where the query power supply needs to be distributed to multiple paths, a query power distribution module can be installed on the backplane of the main control chassis. The power input for the query power distribution module F31 is provided by the field power socket on the backplane of the main control chassis. Figure 5 shows the wiring method for AC power input. Installation system for FM series hardware equipment - MACS10 main controller setup. The right section of the main control chassis is connected to the main control unit module. Two 6-bit DIP switches are used to set the station address of the redundant main control unit; two 4-pin sockets serve as the system power supply (1# and 2# system power) and the output interface for DP communication; four RJ45 sockets are the system network (SNET) output interfaces of the main control unit, as shown in Figure 6. Setting of the main control station number: The DIP switches are numbered from bottom to top as positions 1 to 6.
