2、antum PLC做Modbus主时能够通过 IEC Xmit, Xxmit and 984LL Xmit指令与其它支持Modbus协议的从设备进行Modbus通讯。Xxmit和Xmit指令只能工作在IEC工作方式,Xmit指令比Xxmit指令公布早，从编程配置方便角度动身，编程使用过程中建议使用Xxmit指令。984LL Xmit 功能块应用在984LL中。369,问：请问如何确定Twido操纵器最近一次停机的缘故？系统字%SW58包含了最近一次停机的代码。370,问：Unity Pro安装环境？标准要求 : PC 1.2GHz, 512M Ram, 4 Gb disk space 最小要求

3、 : PC 800Mhz, 256M Ram, 2 Gb disk space只能在Windows 2000 和XP上安装，不支持Windows98操作系统。一台PC机上不能同时安装两个不同版本的UNITY PRO，但能够和PL7 PRO 和 CONCEPT 共存于同一PC 机上。371,问：UNITY PRO光盘中带有MODBUS PLUS DRIVER吗？不带。372,问：安装UNITY PRO软件后，启动时出现错误提示：“Object store internal error, VirtualAlloc failed to allocate at any address - Not en

4、ough storage is available to process this”，是什么缘故？产生这种错误的缘故是：有另外的软件正在使用与UNITYPRO相同的内部存储区。检测的方法是同时运行所有的软件，依次禁止软件运行以推断与哪一个冲突。Powerword, 3721, Twinmos, item都有可能与UNITY PRO 产生冲突。373,问：Unity PRO支持XXMIT指令吗？目前版本Unity PRO（2.0）不支持XXMIT指令。374,问：当在Unity Pro 中打开concept 产生的.asc文件时，出现错误提示“Converter Dll for this ext

5、ension not found”,如何解决？这是由于在安装该软件时选择的是“Typical”,这种安装不包含Concept converter.解决方法：重新插入安装盘，选择“Modify”,再选择相关的converter进行安装，375,问：Concept程序如何样在Unity Pro中打开？需要进行转换。用Concept Converter 将Concept程序导出为一个*.acs文件，在Unity Pro中打开该文件即可。376,问：在unity双机热备系统中，用什么电缆连接两个140cpu67160 CPU？在unity双机热备系统中，用于连接两个140cpu67160 CPU的光纤

6、的订货号为：490NOR00 xx，xx代表以米为单位的长度：03，05，15。377,问：请问Unity Pro的Medium、Large、XLarge三个版本的区不？Unity Pro Medium支持Premium和Atrium PLC；Unity Pro Large支持Premium、Atrium和Quantum PLC；Unity Pro XLarge支持Premium、Atrium、Quantum和Quantum热备PLC。378,问：连接Unity Quantum PLC 140 CPU 6*1*0 到MB+网络的分站电缆是什么型号？用于连接上述PLC的MB+分站电缆为：990

7、NAD 218 10(2.4米) /990 NAD 218 30(6米)379,问：能不能通过Modem实现Concept编程软件和PLC的远程连接, 如能, 如何实现?Concept中的IEC方式支持变址寻址, 先生成一个数组变量XXXARRAY和一个整型变量CONTROL, 则其变址寻址的书写格式为XXXARRAY CONTROL,有关Concept中的IEC方式下的变址寻址有以下注意事项:1. 将PLC前面板的开关位置设置到”MEM”, 然后在Concept中设置PLC的Modbus口参数为: Modbus ASCII, 9600Baud, 7Data Bits, Even Parity

8、, 1 Stop Bit.2. 用标准串行电缆连接Modem和PC串口, 然后进超级终端, 配置串口并建立连接, 串口配置与Modbus口参数一致.3. 打开超级终端连接窗口, 输入相应的AT指令设置Modem, 并测试通讯.4. 输入ATDTxxxx (xxxx是与PLC连接的Modem的号码)进行拨号连接, 若连接成功, 返回”Connected 9600”, 同时Modem上指示灯显示已连接.5. 在超级终端连接窗口中选择”Disconnect”, 断开超级终端和Modem的连接, 但Modem间的连接依旧保留.可从Modem上指示灯推断连接状态.6. 启动Concept, 并与PLC连

9、接7. 要结束连接时, 先退出Concept, 然后通过Modem 断电, 或断开电话线, 或在超级终端连接窗口, 输入相应的AT指令断开拨号连接.380,问：如何卸载Unity Pro?unity pro 安装在4个目录：unity pro Security editor, Unity pro Types Library, Unity pro XL 和Unity pro xl hardware catalog。在操纵面板中用add/remove program分不删除，顺序无要求。381,问：当CPU型号为p57 4634 /5634时，如何配置TSX FPP 20/TSX FPP 200

18、partment.Quantum PLC Modbus Plus PortPosted by Rajesh Sharma on 12 January, 2005 - 12:37 amI had a problem which I am unable to understand. I was checking Quantum PLC 113 for communication by Foxboro DCS & ABB Advant 450. Both DCS dont have Modbus Plus Hardware. We want to establish communication be

19、tween one DCS & quantum PLC.We had used cross RS-232 Cable for communication instead of what is specified by quantum catalog. We had no communication on Modbus Port by Foxboro & ABB DCS. By mistake we had connect RS-232 DCS port to Modbus Plus Port & it start communication. Modbus Plus is not suppos

20、ed to communicate on serial link. We than make RS-232 connection as per quantum catalog Pin 2 & 3 Cross 4 & 6 Cross, 7 & 8 short on both sides 1 & 5 short. After this connection Both DCS start communicate on Modbus Port of Quantum PLC.Now My question why Quantum PLC communicate on RS-232 cross cable

21、 connection on Modbus PLUS port? DCS dont have any Modbus PLUS Hardware. Request All expert to revert back ASAP.Regards Posted by Brad on 13 January, 2005 - 1:21 pmModicon modbus RTU ports are configured for baud rate, parity, data bits etc through the Concept programming package. By default 9600,8,

22、E,1. Now these ports are full hardware handshaking so unless you cross (or tie together on one end) RTS/CTS and DSR,DTR and DTD comms will not work.Your DCS cannot communicate on Modbus PLUS - implossible. Modbus PLUS is a variant of RS485 and is a token passing network.Now I cant remember for the 1

23、13 controllers (it is the case for 434/534 controllers) there are two slide switches on the font panel which changes the communication parameters between what is configured in Concept vs dafult settings of 9600,8,E,1. Check these vs Concept HELP files. Posted by Rajesh Sharma on 17 January, 2005 - 9

24、:01 amDear Mr. Brad,I full agree with you that Modbus PLUS should not communicate on RS-232 cable. But we all Foxboro,ABB engineers had seen by issuing query & getting response on Modbus Plus port. We also confused on this behaviour. Request Pl. answer if you have. We dont have word IMPOSSIBLE becau

25、se there are many cases where Vendors says it is impossible & we had seen same in front of them. Posted by Anonymous on 13 January, 2005 - 3:47 pmDear Rajesh,What you observed like communication, that was something else. Modbus Plus is an RS 485 based network with peer-to-peer communication.Modbus P

26、ort is using RS-232 signaling and different communication stack. Master polls the slaves after each other. In your case the Modbus Port #1 acts as Master port. Your DCS devices as a slave, I think.Ignore that communication signals. Posted by on 13 May, 2009 - 1:24 amModbus Plus protocol uses RS-485

27、for its multi-drop feature and is a Master-Slave protocol. It is supported by many manufactures. I have found it standard (or an option) in many medium voltage protection relays and meters. I suspect Foxboro and ABB offer a Modbus Plus interface module. These interfaces will allow engineers to confi

28、gure tables to specify blocks of boolean/integers/real/word data to & from the PLC.If your DCS has a serial port then use Modbus protocol to pass data between it and the PLC. It uses RS-232 for a point-to-point serial connection. Connect using an off the shelf serial cable c/w null modem between the

29、 DCS serial port and the Quantum CPU534 Comm 1 port or buy a Schneider Modbus communication cable. Set the PLC slider selector switch to RTU and configure communication settings to 9600, even, 8, 1.Have you considered Modbus Plus over Ethernet (MBE)? Posted by balberoz on 25 January, 2010 - 10:47 pmThe cable connection principle are the same device application will be used cross cable connection while for the different application (ex: Pc to sw) will be used direct conne
