固件選項
選擇具有應(yīng)用程序所需功能的固件:
標(biāo)準(zhǔn)-包括閉環(huán)PID控制，自動調(diào)諧，報警，作業(yè)內(nèi)存和失敗的傳感器檢測。擠出機(jī)包括標(biāo)準(zhǔn)固件功能，具有專門適用于塑料擠出機(jī)的pid控制。坡道和浸泡-包括標(biāo)準(zhǔn)固件功能，增加坡道和浸泡和過程變量傳輸。每個通道可以配置為標(biāo)準(zhǔn)pid控制或斜坡和浸泡操作。任何通道上未使用的控制輸出都可以配置為重傳。增強(qiáng)功能-包括標(biāo)準(zhǔn)固件功能，增加了過程變量重傳遠(yuǎn)程模擬設(shè)定點(diǎn)，級聯(lián)控制，比率控制和差分控制算法。每個通道可以配置為標(biāo)準(zhǔn)PID控制器或其他控制算法之一。串級控制或遠(yuǎn)程模擬設(shè)定點(diǎn)的每個通道需要兩個控制器通道。任何通道上未使用的控制輸出都可以配置為重傳。
由于SERIES CLS200沒有板載模擬輸出，因此使用過程變量重傳的應(yīng)用程序通常需要每個重傳信號一個SDAC模塊。

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.
