系統配置基本配置FA-M3 Value版本（F3SC21-1N）包括以下組件F3BU04-0N基本模塊-帶有電源和內存的F3SP05-0P序列CPU模塊-F3WD64-3N I/O模塊如果FA-M3 Value版本出現故障，只能通過更換故障模塊來修復。將F3SP05-0P序列CPU模塊安裝在F3BU04-0N基本模塊的最左側插槽中，并將F3WD64-3N I/O模塊安裝在插槽2中。其余插槽3和4為FA-M3系列可用的各種I/O模塊保留。插槽編號由三位數字組成，其中第三位數字是單元編號。單元編號0分配給主單元。001 002 003 004主機（F3SC21-1N）FB010101.VSD I/O模塊I/O模塊插槽編號p F3SP05 F3WD64圖B1.1單元主機的插槽編號概念安裝了F3SP05-0P序列CPU模塊的單元稱為主機。因此，F3SC21-1N本身就是主單元。子單元子單元用于增加I/O端口的數量。FA-M3系統的Value版本最多可以添加七個子單元，以處理最多2048個I/O點。使用光纖FA總線模塊增加I/O點的數量您可以在主單元和子單元中安裝光纖FA母線或FA總線類型2模塊，并用光纜連接它們。這使得遠程I/O點的分布式布置、I/O點數量的增加以及通過高速、抗噪聲通信控制I/O模塊成為可能。光纖FA總線或FA總線類型2模塊可以安裝在插槽3或插槽4中
模塊位置限制
如果是F3SC21-1N，則將F3SP05-0P安裝在插槽1中，將F3WD64-3N安裝在插槽2中。其余插槽3和4保留用于FA-M3系列的各種I/O模塊。插槽3和4中不能安裝CPU模塊。有關I/O模塊（包括子單元）安裝的限制，請參閱第A1.2節“模塊安裝限制”，因為它們等同于該節中討論的F3SP21-0N模塊的限制。B1.2.2電流消耗的限制在設計系統時，確保安裝在插槽3和4中的模塊消耗的總電流不超過以下計算值。見第A2.9節，“模塊電流消耗表”。F3SP05-0P模塊的電流供應能力=2000 mA F3SP005-0P模塊CPU的電流消耗=350 mA F3BU04-0N模塊的電流消耗=50 mA F3WD64-3N模塊的當前消耗=200 mA因此，插槽3和4的可用電流總量為2000–350–50–200=1400 mA■ 使用FA總線類型2模塊增加I/O點數的示例與光纖FA總線型號2模塊一樣，可以使用FA母線類型2模塊來增加I/O點數。FA總線類型2模塊使用屏蔽雙絞線連接子單元
System Configuration
Basic Configuration The FA-M3 Value version (F3SC21-1N) consists of the following components. - F3BU04-0N base module - F3SP05-0P sequence CPU module with a power supply and memory - F3WD64-3N I/O module Should the FA-M3 Value version fail, it can be fixed by replacing the failed module only. Install the F3SP05-0P sequence CPU module in the leftmost slot of the F3BU04-0N base module and the F3WD64-3N I/O module in slot 2. The remaining slots 3 and 4 are reserved for a variety of I/O modules available for use with the FA-M3 series. A slot number consists of three digits of which the third digit is the unit number. The unit number 0 is allocated to the main unit. 001 002 003 004 Main unit (F3SC21-1N) FB010101.VSD I/O module I/O module Slot number p F3SP05 F3WD64 Figure B1.1 Slot Numbering ? Concept of Unit Main Unit A unit in which the F3SP05-0P sequence CPU module is installed is referred to as a main unit. Consequently, the F3SC21-1N itself serves as the main unit. Subunit Subunits are used to increase the number of I/O ports. A maximum of seven subunits can be added to the Value version of the FA-M3 system to deal with up to 2048 I/O points. ? Increasing the Number of I/O Points Using Fiber-optic FA-bus Modules You can install fiber-optic FA-bus or FA-bus type 2 modules in both main and subunits and connect them with fiber-optic cables. This enables the distributed arrangement of remote I/O points, increase in the number of I/O points, and control of I/O modules via high-speed, noise-immune communication. The fiber-optic FA-bus or FA-bus type 2 module may be installed in either slot 3 or slot 4
Restrictions on Module Location
In the case of the F3SC21-1N, install the F3SP05-0P in slot 1 and the F3WD64-3N in slot 2. The remaining slots 3 and 4 are reserved for a variety of I/O modules available for use with the FA-M3 series. No CPU module can be installed in slots 3 and 4. For restrictions on the installation of I/O modules, including subunits, refer to Section A1.2, “Restrictions on Module Installation,” as they are equivalent to the restrictions specified for the F3SP21-0N module discussed in that section. B1.2.2 Restrictions due to Current Consumption Make sure when designing your system that the total sum of current consumed by modules installed in slots 3 and 4 does not exceed the following calculated value. See section A2.9, "Module Current Consumption Tables". Current-supply capacity of the F3SP05-0P module = 2000 mA Current consumption by the CPU of the F3SP05-0P module = 350 mA Current consumption of the F3BU04-0N module = 50 mA Current consumption of the F3WD64-3N module = 200 mA Consequently, the total amount of current available from slots 3 and 4 is 2000 – 350 – 50 – 200 = 1400 mA■ Example of increasing the number of I/O points using FA-bus type 2 modules As with fiber-optic FA-bus type 2 modules, the number of I/O points can be increased using FA-bus type 2 modules. FA-bus type 2 modules use shielded twisted-pair cables for the connection between subunits.
