# secs4net [](https://www.nuget.org/packages/secs4net/) **Project Description** SECS-II/HSMS-SS/GEM implementation on .NET. This library provide easy way to communicate with SEMI standard compatible device. 1\. Send message to device ```cs try { //await secondary message var s3f18 = await device.SendAsync(s3f17); //access item value byte b1 = (byte)s3f18.SecsItem.Items[0]; byte b2 = s3f18.SecsItem.Items[0].GetValue<byte>(); string str = s3f18.SecsItem.Items[0].GetString(); // LINQ query var query = from a in s3f18.SecsItem.Items[3].Items select new { num = a.GetValue<int>(), }; } catch(SecsException) { // exception when // T3 timeout // device reply SxF0 // device reply S9Fx } ``` 2\. Handle primary message from device ```cs secsGem.PrimaryMessageReceived += async (sender, messageWrapper) => { try { //do something for primaryMsg var primaryMsg = messageWrapper.Message; // reply secondary msg to device await messageWrapper.ReplyAsync( secondaryMsg ); } catch (Exception ex) { } }; ``` 3\. SecsMessage/Item construction is also LINQ friendly ```cs using static Secs4Net.Item; var s16f15 = new SecsMessage(16, 15, "CreateProcessJob" L( U4(0), L(from pj in tx.ProcessJobs select L( A(pj.Id), B(0x0D), L(from carrier in pj.Carriers select L( A(carrier.Id), L(from slotInfo in carrier.SlotMap select U1(slotInfo.SlotNo)))), L( U1(1), A(pj.RecipeId), L()), Boolean(true), L())))); ``` 4\. SecsMessage/Item is immutable(API level).
