Section１Before Using the Product

１．１． Aboutthe OperationManual

Thismanualexplainsthecommunication functionofTRM-00J.

１．２． Requirements for Communication

Asastandardfeatureforcommunication,this productisequippedwithRS-485and USB communicationfunction.

１．３． ThingsCommunicationFunction CanDo

Allows usertowriteandreadtoitemsofthisproductthataredescribed in “Section６ListofIdentifiers” such as “To change, start, or stop

items that can be operated through front keys” and “To read the information that can be displayed on the display section.”

Provided,however,thatsincetheRAMofthisproductisusedduringthereading/writingofdatathrough ordinarycommand,thedata

thatwaswrittenwillbereplacedbythe previousdata(datathatissavedinEEPROM)ifthepoweristurnedOFFandthenturnedON.

TosavethewrittendataintotheEEPROMofthisproduct, executethesaverequest message.

(See “４．５．”, “５．１．４．” and “５．２．４．” Things to Be Noted during the Communication.)

１．４． Position(Priority)ofCommunication

This product allows the user to change parameters through the key (including touch operation, hereinafter referred to as “key

operation”) even during the communication. Although the same setting can be changed simultaneously through key operationand

communication,donot changethesettingthroughcommunicationwhilethesetting is beingeditedthroughkeyoperation sincethereis

noprioritybetweenkeyoperationandcommunication.

１．５． Settingsto BeMadePrior totheCommunication

Several settings need to be made to this product in order for it to perform a communication function. See “Section２Communication

During thesettingofMODBUSRTU,data lengthwillbefixedto8bits(data lengthsettingwillbeignored).

２．６． Settingof BCC

In case of TOHO Protocol, set “With or Without BCC Check (Turn BCC Check ON/OFF).”

２．７． Settingof Response Delay Time

Setthetime to take for the upper computer to complete the receiving of “request message,” open the line, and get ready for the next

input.
