A4H254-8F8T交換機(jī)模塊,A4H254-8F8T使用數(shù)據(jù)
90-30系列配置16通道模擬電流輸入模塊手持式編程器。除本節(jié)中的信息外，請(qǐng)參閱GFK-0402
系列90-30/20/Micro可編程控制器的手持編程器用戶手冊(cè)有關(guān)智能輸入/輸出模塊配置的更多信息。盡管您可以使用Logicmaster更改活動(dòng)掃描通道的數(shù)量90-30/20/Micro配置程序功能，手持編程器不支持編輯活動(dòng)掃描通道的數(shù)量。
A4H254-8F8T交換機(jī)模塊如果16通道模擬輸入模塊由初始化作為一個(gè)手持式編程器，主動(dòng)掃描通道的數(shù)量為16個(gè)。如果模塊先前已配置Logicmaster 90-30/20/Micro軟件和活動(dòng)掃描通道的數(shù)量已從16個(gè)更改，將顯示該數(shù)量在手持式編程器顯示屏的底線上，跟隨AI。您可以編輯數(shù)據(jù)用手持式編程器只用于活動(dòng)信道，但不能改變信道數(shù)主動(dòng)掃描通道。
模塊存在如果模塊實(shí)際存在于系統(tǒng)中，則可以通過以下方式將其添加到系統(tǒng)配置中：將模塊讀入其中。例如，假設(shè)16通道模擬電流輸入模塊安裝在311型PLC系統(tǒng)的插槽3中?？梢詫⑵涮砑拥脚渲弥邪凑找韵马樞?。使用上下光標(biāo)鍵或#鍵顯示所選插槽。手持式編程器無法更改此字段。然而，它可以是使用Logicmaster 90-30/20/20/Micro軟件配置器功能進(jìn)行更改。手持編程器將始終反映sta tus字段的當(dāng)前活動(dòng)長(zhǎng)度。按下ENT鍵將允許PLC選擇狀態(tài)數(shù)據(jù)的起始地址。你可以按所需地址的鍵序列選擇特定的起始地址，然后按ENT鍵。例如，要將起始地址指定為I17，請(qǐng)按鍵序列1，7，ENT。將顯示以下屏幕：
using the Series 90-30
Hand-Held Programmer. In addition to the information in this section, refer to GFK-0402, the
Hand-Held Programmer for Series 90-30/20/Micro Programmable Controllers User’s Manual
for more information on configuration of Intelligent I/O modules.
Although you can change the number of actively scanned channels with the Logicmaster
90-30/20/Micro configurator function, the Hand-Held Programmer does not support editing the
number of actively scanned channels. If the 16-Channel Analog Input module is initialized by
a Hand-Held Programmer, the number of actively scanned channels is 16.
If a module had been previously configured with Logicmaster 90-30/20/Micro software and the
number of actively scanned channels has been changed from 16, that number will be displayed
on the bottom line of the Hand-Held Programmer display following the AI. You can edit data
with the Hand-Held Programmer only for the active channels, but can not change the number of
actively scanned channels.
Module Present
If a module is physically present in a system, it can be added to the system’s configuration by
reading the module into it. For example, assume that a 16-Channel Analog Current Input
module is installed in slot 3 of a Model 311 PLC system. It can be added to the configuration
with the following sequence. Use the Up and Down cursor keys or the # key to display the
selected slot.This field cannot be changed with the Hand-Held programmer. However, it can be
changed using the Logicmaster 90-30/20/20/Micro software configurator function.
