A4H254-8F8T交換機模塊,A4H254-8F8T使用數據
90-30系列配置16通道模擬電流輸入模塊手持式編程器。除本節中的信息外,請參閱GFK-0402
系列90-30/20/Micro可編程控制器的手持編程器用戶手冊有關智能輸入/輸出模塊配置的更多信息。盡管您可以使用Logicmaster更改活動掃描通道的數量90-30/20/Micro配置程序功能,手持編程器不支持編輯活動掃描通道的數量。
A4H254-8F8T交換機模塊如果16通道模擬輸入模塊由初始化作為一個手持式編程器,主動掃描通道的數量為16個。如果模塊先前已配置Logicmaster 90-30/20/Micro軟件和活動掃描通道的數量已從16個更改,將顯示該數量在手持式編程器顯示屏的底線上,跟隨AI。您可以編輯數據用手持式編程器只用于活動信道,但不能改變信道數主動掃描通道。
模塊存在如果模塊實際存在于系統中,則可以通過以下方式將其添加到系統配置中:將模塊讀入其中。例如,假設16通道模擬電流輸入模塊安裝在311型PLC系統的插槽3中。可以將其添加到配置中按照以下順序。使用上下光標鍵或#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軟件配置器功能進行更改。手持編程器將始終反映sta tus字段的當前活動長度。按下ENT鍵將允許PLC選擇狀態數據的起始地址。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.
