1400-PD51A電源監(jiān)視器
數(shù)據(jù)區(qū)域大小的限制確定所有I/O模塊（即不包括電源和CPU模塊的模塊）提供的數(shù)據(jù)區(qū)域的總大小M。然后檢查M的值是否符合數(shù)據(jù)區(qū)域最大大小的限制。數(shù)據(jù)區(qū)M的總大小取決于I/O模塊的安裝順序。根據(jù)您的應(yīng)用需求，提前考慮系統(tǒng)配置，包括子單元數(shù)量、單元編號和I/O模塊的安裝位置。z由于數(shù)據(jù)區(qū)域大小的限制定義為M≤ 112+32×（4-n），其中n=CPU模塊數(shù)。此處的值112和32是由于CPU模塊的功能規(guī)格而造成的限制。z計算程序按順序匯總所有I/O模塊的數(shù)據(jù)區(qū)域大小，從主機(jī)插槽1到第七個子單元插槽16，以確定總大小M。如果有數(shù)據(jù)區(qū)域大小為4、8或16的I/O模塊，則將數(shù)據(jù)區(qū)域大小的運(yùn)行總數(shù)四舍五入到最接近的4、8和16的倍數(shù)，然后再添加該I/O模塊的大小。示例：如果系統(tǒng)配置了以下模塊，則總數(shù)據(jù)區(qū)域M為56。如果使用光纖FA總線類型2模塊將子單元劃分為組，則插槽總數(shù)可能會小于上述值，具體取決于此類劃分的模式。有關(guān)總金額計算的更多信息，請參閱光纖FA總線模塊和光纖FAbus 2型模塊、FA總線2型模塊（IM 34M06H45-01E）。數(shù)據(jù)區(qū)M的總大小取決于模塊的安裝順序。如果初始系統(tǒng)配置不符合任何給定限制，請嘗試通過串行安裝相同數(shù)據(jù)區(qū)域大小的I/O模塊來更改模塊的安裝順序。此策略可以實現(xiàn)對限制的遵從。
對于順序CPU模塊類型
確定分配給序列CPU模塊的I/O模塊提供的I/O點的總和R。然后檢查R的值是否符合最大I/O點數(shù)的限制。分配給CPU模塊的I/O模塊是指那些實際安裝并設(shè)置為Configuration（配置）菜單的Use（使用）選項的模塊。如果安裝了兩個或更多CPU模塊，請檢查每個模塊是否符合要求。z當(dāng)CPU模塊為F3SP21 R時≤2048 z當(dāng)CPU模塊為F3SP22/25/28/53/66/71或F3FP36 R時≤4096 z當(dāng)CPU模塊為F3SP35/38/58/59/67/76 R時≤8192另見I/O模塊分配的詳細(xì)信息，請參閱梯形圖支持程序M3（IM 34M06Q13-01E）中的FA-M3編程工具WideField3（IM 34 M06Q16-xxE）、FA-M3程序工具WideField 2（IM 36 M06Q15-01E）、FA-M3編程工具WideFild（IM 39 M06Q14-01E）或第6.6節(jié)“輸入配置項目”。確定I/O模塊為分配I/O模塊的BASIC CPU模塊提供的工作區(qū)總數(shù)D。然后檢查D值是否符合BASIC CPU工作區(qū)大小的限制。分配給CPU模塊的I/O模塊是指那些由BASIC程序中的ASSIGN語句聲明其用途的模塊。在確定BASIC CPU工作區(qū)的總和D時要小心，因為工作區(qū)是十六進(jìn)制的。z當(dāng)CPU模塊為F3BP20或F3BP30 D時≤$2900值$2900受CPU模塊的功能規(guī)格限制。另請參閱“BASIC CPU modules and YM-BASIC/FA Programming Language”（IM 34M06Q22-01E）中的第B7.3節(jié)“I/O模塊使用聲明”，了解I/O模塊分配的詳細(xì)信息。
Restrictions due to the Size of Data Area
Determine the total size M of the data area provided by all I/O modules (i.e., modules excluding the power supply and CPU modules). Then check that the value of M complies with restrictions placed by the maximum size of data area. The total size of data area M varies depending on the order in which I/O modules are installed. Consider system configuration in advance, including the number of subunits, unit number and I/O modules’ installation locations, according to your application needs. z Restrictions due to the size of data area are defined as M ≤ 112 + 32 × (4 - n), where n = the number of CPU modules. The values 112 and 32 here are the limits due to the function specifications of the CPU modules. z Calculation Procedure Sum up the sizes of data areas in sequence for all I/O modules, starting from slot 1 of the main unit up to slot 16 of the 7th subunit to determine the total size M. If there is any I/O module with a data-area size of 4, 8 or 16, then round up the running total for the data area sizes to the nearest multiple of 4, 8 or 16 before you add the size of that I/O module. Example: If the system is configured with the following modules, the total data area M is 56. If subunits are divided into groups using fiber-optic FA-bus type 2 modules, the total number of slots may become smaller than the value noted above depending on the mode of such division. For more information on the calculation of the total sum, see the Fiber-optic FA-bus Module and Fiber-optic FAbus Type 2 Module, FA-bus Type 2 Module (IM 34M06H45-01E).The total size of data area M varies depending on the order in which modules are installed. If the initial system configuration fails to comply with any given restriction, try changing the order in which modules are installed by serially installing I/O modules of the same data-area size, for example. This strategy may achieve compliance with the restriction.
For Sequence CPU Module Type
Determine the total sum R of I/O points provided by I/O modules allocated to the sequence CPU module. Then check that the value of R complies with restrictions placed by the maximum number of I/O points. The I/O modules allocated to the CPU module refer to those that are actually installed and set to the Use option of the Configuration menu. If two or more CPU modules are installed, check each of them for compliance. z When the CPU module is F3SP21 R≤2048 z When the CPU module is F3SP22/25/28/53/66/71 or F3FP36 R≤4096 z When the CPU module is F3SP35/38/58/59/67/76 R≤8192 SEE ALSO For details on the allocation of I/O modules, see FA-M3 Programming Tool WideField3 (IM 34M06Q16- xxE), FA-M3 Programming Tool WideField2 (IM 34M06Q15-01E), FA-M3 Programming Tool WideField (IM 34M06Q14-01E) or Section 6.6, “Entering Configuration Items,” in the Ladder Diagram Support Program M3 (IM 34M06Q13-01E).Determine the total sum D of work areas provided by I/O modules for the BASIC CPU module to which the I/O modules are allocated. Then check that the value of D complies with restrictions due to the size of the BASIC CPU’s work area. The I/O modules allocated to the CPU module refer to those whose use is declared by the ASSIGN statement in the BASIC program. Be careful when determining the total sum D of the BASIC CPU’s work area since the work areas are in hexadecimal. z When the CPU module is F3BP20 or F3BP30 D≤$2900 The value $2900 is limited by the function specifications of the CPU module. SEE ALSO For details on the allocation of I/O modules, see Section B7.3, “Declaration of Use of I/O Modules” in the “BASIC CPU Modules and YM-BASIC/FA Programming Language” (IM 34M06Q22-01E).
