【产品详情】

1785-V80B处理器属于PLC-5系列处理器。该处理器具有与增强型PLC-5处理器PLC-5/80相同的指令集。此外，1785-V80B还符合C.1 VMEbus规范。这意味着1785-V80B处理器可以直接连接到VMEbus系统总线，1785-V80B可以与其他VMEbus CPU模块一起使用。1785-V80B可以通过VMEbus通信接口与VMEbus I/O模块接口。1785-V80B处理器不使用EEPROM内存模块。

1785-V80B的内存最多可达100,000个单词，每个数据表文件的限制为32,000个单词。1785-V80B可以处理总共2944个I/O，这些I/O可以互补排列，其中2944个为输入I/O, 2955个为输出I/O。2944个模拟I/O可通过1785-V80B寻址。

1785-V80B具有具有位逻辑的程序扫描时间为每1000个字0.5 ms，或典型的每1000个字2 ms。扩展的本地I/O扫描时间为0.5 ms，传输速率为57.6 kbps时每个机架扫描时间为10 ms，传输速率为115.2 kbps时为7ms，传输速率为230 kbps时为3 ms。

1785-V80B有以下几种传输速率:57.6 kbps、115.2 kbps和230 kbps。

1785-V80B处理器有4个端口，可以配置为DH+或远程I/O端口，但没有端口用于扩展本地I/O端口。1785-V80B最大可接入的I/O机架数为23个。可以远程连接的I/O机箱最多为92个，不能将I/O机箱作为扩展本地连接。该处理器有一个RS232端口。

在1785-V80B的前面板上，有0、1A、1B、2A、2B四个通信通道。

通道0有一个25针的d壳连接器。它是一个光耦合串行端口，支持EIA RS-232C，支持ASCII或DF1协议。通道1A、1B、2A和2B各有一个3针连接器。它具有用户可配置的端口，支持扫描仪、适配器和数据高速公路Plus (DH+)通信模式。

编程终端配备8针mini-DIN连接器(2 -连接器)，用于编程目的。

【英文介绍】

The 1785-V80B processor belongs to the PLC-5 series of processors. The processor has the same instruction set as the enhanced PLC-5 processor PLC-5/80. In addition, the 1785-V80B conforms to the C.1 VMEbus specification. This means that the 1785-V80B processor can be connected directly to the VMEbus system bus, and the 1785-V80B can be used with other VMEbus CPU modules. The 1785-V80B can interface with the VMEbus I/O module through the VMEbus communication interface. The 1785-V80B processor does not use an EEPROM memory module.

The 1785-V80B has a memory of up to 100,000 words, with a limit of 32,000 words per datasheet file. The 1785-V80B can handle a total of 2,944 I/ OS, which can be arranged in a complementary manner, of which 2,944 are input I/ OS and 2,955 are output I/ OS. 2944 analog I/ OS can be addressed with the 1785-V80B.

The 1785-V80B has a program scan time of 0.5 ms per 1000 words with bit logic, or a typical 2 ms per 1000 words. The extended local I/O scan time is 0.5 ms, the scan time per rack is 10 ms at a transfer rate of 57.6 kbps, the transfer rate is 7ms at 115.2 kbps, and the transfer rate is 3 ms at 230 kbps.

The 1785-V80B is available at the following transmission rates :57.6 kbps, 115.2 kbps, and 230 kbps.

The 1785-V80B processor has four ports that can be configured as DH+ or remote I/O ports, but no ports to extend local I/O ports. The 1785-V80B supports a maximum of 23 I/O racks. A maximum of 92 I/O chassis can be connected remotely. I/O chassis cannot be used as an extended local connection. The processor has an RS232 port.

On the front panel of the 1785-V80B, there are four communication channels 0, 1A, 1B, 2A and 2B.

Channel 0 has a 25-pin D-shell connector. It is an optically coupled serial port that supports EIA RS-232C and supports either ASCII or DF1 protocols. Channels 1A, 1B, 2A, and 2B each have a 3-pin connector. It has a user-configurable port that supports scanner, adapter, and Data Highway Plus (DH+) communication mode.

The programming terminal is equipped with an 8-pin mini-DIN connector (2-connector) for programming purposes.
