YS1700-000/A34  YS1700可编程指示控制器

YS1700可编程指示控制器可以通过运行用户程序为各种应用进行定制，并通过横河电机的专有技术、用户友好性和可扩展性提高可靠性。与之前的系列相比，标准型号更小巧轻便，安装所需空间更小，并且符合包括CE标志和FM非易燃(可选)认证在内的国际安全标准。为了方便更换早期控制器，需要同时提供与早期型号相同的面板开孔尺寸和深度。

主要特点

• 采用全点阵彩色LCD，清晰度出色：即使在清晨和傍晚阳光直射下，也能确保显示屏高度可见。用户可以从仪表、趋势、条形图、报警和事件显示中自由访问所需的操作画面。可以通过前面板显示设置所有参数。
• 功能块编程：除了与早期型号兼容的文本编程外，YS1700还提供基于GUI的新编程方法—功能块编程。YS1000系列的可选YSS1000设定软件用于开发用户程序。.
• 编程容量大：文本程序的程序容量为1000步，功能块程序为400个模块。
• 控制和计算功能更强大：通过IEEE754格式4字节浮点计算，可将实际值用于计算。具备100多种计算模块，包括指数函数和对数函数、温度补偿和压力补偿。
• 功能选择模式(无需编程)：在多功能控制器模式下，无需编程即可从使用频率高的功能(单回路、级联或选择器控制)中选择控制。可通过参数设置确定数字和模拟输入/输出(DI、DO、AI和AO)的功能分配。
• 扩展I/O：带扩展I/O的基本型具有8个模拟输入、4个模拟输出、10个数字输入或10个数字输出(共14个数字输入和输出)。
• Fail-safe：由于具有双CPU (一个用于控制，一个用于显示)，因此，即使其中一个CPU故障，也能够进行显示和手动操作。当包含2个CPU的数字电路故障时，可以通过独立于数字电路的硬手动电路对控制器输出进行手动调整。(指定/NHM可选项时，不包含硬手动电路。)
• 非易失性存储器用于内存备份：无需使用电池或电容器进行内存备份，便于维护。
• AC/DC双电源的工作电压范围广，可确保电源电压波动时的稳定性：可使用AC(100 V)或DC(24 V)电源进行供电。另外，DC电源还可以接收无极性电力。(若使用220 V AC电源，必须在订购时指定。)
• 深度为250 mm (仅基本型)
• 防尘/防滴IP54面板(仅基本型)
• CE标志(仅基本型和YS100兼容型)
• FM非易燃防爆保护(仅基本型可选)
• 通信(可选项) – 以太网(Modbus/TCP；仅基本型) – RS485 (PC Link、Modbus、点对点通信和YS协议；不适用于YS80内部单元兼容型) – DCS-LCS通信
• 与YS100系列兼容：能够以相同方式进行设定和控制操作。对于基本型，终端到终端的间距不同，但是信号到终端的分布几乎相同。

YS1700-000A34

The YS1700 programmable indicating controller can be customized for a variety of applications by running user programs and improves reliability through Yokogawa Electric’s proprietary technology, user friendliness and scalability. Compared to the previous series, the standard model is smaller and lighter, requires less space for installation, and meets international safety standards including CE marking and FM non-flammable (optional) certification. To facilitate the replacement of earlier controllers, it is necessary to provide the same panel opening size and depth as earlier models at the same time.

Main feature
Excellent clarity with a full dot-matrix color LCD: the display is highly visible even in direct sunlight in the early morning and late afternoon. Users can freely access the desired action screen from the meter, trend, bar chart, alarm and event display. All parameters can be set through the front panel display.
Feature block Programming: In addition to text programming that is compatible with earlier models, the YS1700 also offers a new GUI-based programming method – feature block programming. Optional YSS1000 setup software for the YS1000 series is used to develop user programs. .
Large programming capacity: the program capacity of the text program is 1000 steps, and the function block program is 400 modules.
More powerful control and calculation: with IEEE754 format 4-byte floating point calculation, the actual value can be used for calculation. More than 100 calculation modules are available, including exponential and logarithmic functions, temperature compensation and pressure compensation.
Function Selection mode (no programming required) : In multi-function controller mode, you can select controls from frequently used functions (single loop, cascade, or selector controls) without programming. The function assignment of digital and analog inputs/outputs (DI, DO, AI, and AO) can be determined through parameter Settings.
Extended I/O: The basic model with extended I/O has 8 analog inputs, 4 analog outputs, 10 digital inputs, or 10 digital outputs (a total of 14 digital inputs and outputs).
Fail-safe: Because it has two cpus (one for control and one for display), display and manual operations can be performed even if one of the cpus fails. When a digital circuit containing 2 cpus fails, the controller output can be manually adjusted by a hard manual circuit independent of the digital circuit. (Hard manual circuits are not included when specified /NHM is optional.)
Non-volatile memory for memory backup: no need to use batteries or capacitors for memory backup, easy maintenance.
The wide operating voltage range of the AC/DC dual power supply ensures stability when the power supply voltage fluctuates: It can be supplied with an AC(100 V) or DC(24 V) power supply. In addition, the DC power supply can also receive non-polar power. (If 220 V AC power is used, it must be specified when ordering.)
Depth 250 mm (basic model only)
Dustproof/drip-proof IP54 panel (basic model only)
CE mark (basic model and YS100 compatible model only)
FM Non-flammable and explosion-proof protection (optional for basic model only)
Communication (optional) – Ethernet (Modbus/TCP; Basic model only) – RS485 (PC Link, Modbus, point-to-point communication and YS protocol; Not applicable to YS80 internal unit compatible) -DCS-LCS communication
Compatible with the YS100 series: can be set up and controlled in the same way. For the basic model, the terminal to terminal spacing is different, but the signal to terminal distribution is almost the same.
