固件选项
选择具有应用程序所需功能的固件:
标准-包括闭环PID控制，自动调谐，报警，作业内存和失败的传感器检测。挤出机包括标准固件功能，具有专门适用于塑料挤出机的pid控制。坡道和浸泡-包括标准固件功能，增加坡道和浸泡和过程变量传输。每个通道可以配置为标准pid控制或斜坡和浸泡操作。任何通道上未使用的控制输出都可以配置为重传。增强功能-包括标准固件功能，增加了过程变量重传远程模拟设定点，级联控制，比率控制和差分控制算法。每个通道可以配置为标准PID控制器或其他控制算法之一。串级控制或远程模拟设定点的每个通道需要两个控制器通道。任何通道上未使用的控制输出都可以配置为重传。
由于SERIES CLS200没有板载模拟输出，因此使用过程变量重传的应用程序通常需要每个重传信号一个SDAC模块。

WATVIEW Software
WATVIEW is an optional Windows-based human machineinterface (HMl) program that can be used as the primaryinterface to one or more Watlow controllers. WATVIEWprovides channel setup and monitoring of up to 32 controllersat the same time. The easy-to-use graphical user interface(GUl) allows you to set control parameters, createuser-defined recipes, view and manage alarms, set up andview trend plots and real-time data and export logged datato spreadsheet applications. Because it is designedspecifically for Watlow controllers, WATVIEW requires lessconfiguration time than other more expensive packages.
DAC and SDAC ModulesThe optional DAC and SDAC modules are available for
Watlow SERIES CLS200 controllers.DACThe DAC (digital to analog converter) converts one or twoof the controller’s distributed zero crossing (DZC) outputsignals to analog signals. Each output is field configurable for4-20mA=(dc),0-5V-(dc) or 0-10V=(dc)SDAC
The SDAC (serial digital to analog converter) convertsone controller output to a precise analog voltage orcurrent signal. The unit is typically used for process variableretransmit, open-loop control, motor or belt speed control,or phase-angle fired SCR power controllers. The SDACbears the CE mark and is UL and C-UL listed.

Firmware Options
Choose firmware with the features needed for theapplication:
Standard-includes closed-loop PID control, auto-tune,alarms, job memory and failed sensor detection.. Extruder includes the standard firmware features, withPID control specifically adapted for plastic extruders.Ramp and soak-includes the standard firmware featureswith the addition of ramp and soak and process variableretransmit. Each channel can be configured for standardPID control or ramp and soak operation. Unused controloutputs on any channel can be configured for retransmition.Enhanced features- includes the standard firmwarefeatures with the addition of process vaniable retransmitremote analog set point, cascade control, ratio controlａnd differential control algorithms. Each channel can beconfigured for standard PID controller or one of the othercontrol algorithms. Each channel of cascade control orremote analog set point requires two controller channels.Unused control outputs on any channel can be configuredfor retransmit.
Because the SERIES CLS200 has no onboard analogoutputs, applications that use process variable retransmittypically require one SDAC module per retransmitted signal.
