YOKOGAWA CP451-51輸出模塊,CP451-51英文使用說(shuō)明
如通道1所述，編輯范圍、低報(bào)警限和高報(bào)警限。所有活動(dòng)通道可以以這種方式更改。按ENT鍵或返回初始顯示屏按← 鍵，直到顯示初始屏幕。保存的配置包含16通道模擬電流輸入模塊的配置可以保存到EEPROM或MEM卡，稍后讀入CPU。MEM卡和EEPROM包含這些配置的內(nèi)容可以讀入任何版本4或更高版本的CPU。請(qǐng)參閱第章有關(guān)保存和恢復(fù)操作。
YOKOGAWA CP451-51輸出模塊從用戶設(shè)備連接到此模塊是為了在可拆卸的安裝在模塊前部的20端子連接器塊。實(shí)際使用的端子為如下表所述，并在以下接線圖中顯示。端子分配16通道模擬電流輸入上20端子輸入/輸出連接器的引腳分配模塊如下表所示。90-30系列可編程邏輯的2通道模擬電壓輸出模塊控制器提供兩個(gè)輸出通道，每個(gè)通道能夠轉(zhuǎn)換13位二進(jìn)制（數(shù)字）數(shù)據(jù)連接到模擬輸出，以便根據(jù)應(yīng)用程序的需要使用。模擬電壓輸出模塊為能夠提供-10至+10伏范圍內(nèi)的輸出。轉(zhuǎn)換信號(hào)的分辨率為12位二進(jìn)制加號(hào)，有效為13位（8192中的1部分）。兩個(gè)頻道都在每次掃描（約5毫秒）。%AQ寄存器中的用戶數(shù)據(jù)是16位2的補(bǔ)碼總體安排%AQ寄存器中的13個(gè)最高有效位通過(guò)以下方式轉(zhuǎn)換為符號(hào)幅度：PLC并發(fā)送至模塊，供D/A轉(zhuǎn)換器電路使用。13的位置轉(zhuǎn)換為符號(hào)幅度的位如下所示。電壓輸出和
D/A轉(zhuǎn)換器的數(shù)據(jù)如圖3-30所示。
Edit the range, and low and high alarm limits as described for Channel 1. All active channels
can be changed in this manner. Return to the initial display screen by pressing the ENT key or
by pressing the ← key until the initial screen is displayed.
Saved Configurations
Configurations that contain a 16-Channel Analog Current Input module can be saved to an
EEPROM or MEM card and read into the CPU at a later time. MEM cards and EEPROMs
containing these configurations can be read into any Release 4 or later CPU. Refer to Chapter
2 of the Hand-Held Programmer User’s Manual for detailed information on the Save and
Restore operations.Connections to this module from user devices are made to screw terminals on a removable
20-terminal connector block mounted on the front of the module. The actual terminals used are
described in the following table and are shown in the following wiring diagrams.
Terminal Assignments
Pin assignments for the 20 terminal I/O connector on the 16-Channel Analog Current Input
module are as shown in the following table.The 2-Channel Analog Voltage Output module for the Series 90-30 Programmable Logic
Controller provides two output channels, each capable of converting 13 bits of binary (digital) data
to an analog output for use as required by your application. The Analog Voltage Output module is
capable of providing outputs in the range of –10 to +10 volts. Resolution of the converted signal is
12 bits binary plus sign which is effectively 13 bits (1 part in 8192). Both channels are updated on
