1: GENERAL INFORMATION Introduction This chapter describes general information about the powerful capabilities of the upgraded FC5A series MicroSmart micro programmable logic controllers and system setups to use the MicroSmart in various ways of communication. About the MicroSmart IDEC’s FC5A MicroSmart is an upgraded family of micro programmable logic controllers available in two styles of CPU modules; all‐in‐one and slim types. The all‐in‐one type CPU module has 10, 16, or 24 I/O terminals and is equipped with a built‐in universal power supply to operate on 100 to 240V AC, or 24 or 12V DC. Using four optional 16‐point I/O modules, the 24‐I/O type CPU module (except 12V DC power type) can expand the I/O points up to a total of 88 points. Program capacity of the all‐in‐one type CPU modules is 13,800 bytes (2,300 steps) on the 10‐I/O type CPU module, 27,000 bytes (4,500 steps) on the 16‐I/O type, and 54,000 bytes (9,000 steps) on the 24‐I/O type. The slim type CPU module has 16 or 32 I/O terminals and operates on 24V DC. The total I/O points can be expanded to a maximum of 512. When using two AS‐Interface master modules, a maximum of 1,380 I/O points can be connected. The program capacity of slim type CPU modules is 62,400 bytes (10,400 steps). Slim type CPU modules feature Logic Engine for superior ladder processing capabilities to achieve fast execution of instructions — 0.056 µs for a basic instruction (LOD) and 0.167 µs for an advanced instruction (MOV). User programs for the MicroSmart can be edited using WindLDR on a Windows PC. Since WindLDR can load existing user programs made for IDEC’s previous PLCs such as OpenNet Controller and FC4A MicroSmart, your software assets can be used in the new control system. Features Powerful Communication Functions The MicroSmart features five powerful communication functions. Maintenance Communication (Computer Link) When a MicroSmart CPU module is connected to a computer, operating status and I/O status can be monitored on the computer, data in the CPU can be monitored or updated, and user programs can be downloaded and uploaded. All CPU modules can set up a 1:N computer link system to connect a maximum of 32 CPU modules to a computer. User Communication All MicroSmart CPU modules can be linked to external RS232C devices such as computers, printers, and barcode readers on port 1 to port 7, using the user communication function. RS485 user com‐ munication is also available on port 2 to port 7. Expansion communication modules (FC5A‐SIF2/‐SIF4) can be used with all‐in‐one 24‐I/O (except 12V DC power type) and slim type CPU modules to expand up to five or seven communication ports, respectively. Modem Communication All MicroSmart CPU modules can communicate through modems using the built‐in modem protocol. Modem communication is available through port 2. Data Link All MicroSmart CPU modules can be used as data link master or slave station. One CPU module at the master station can communicate with 31 slave stations through an RS485 line to exchange data and perform distributed control effectively. Modbus Communication All MicroSmart CPU modules can be used as Modbus master or slave, and can be connected to other Modbus devices. Modbus Master communication is available on port 2 to port 7. Modbus Slave com‐ munication is available on port 1 to port 7. FC5A MicroSmart User’s Manual FC9Y‐B1268 1‐1
