Open Protocol is an open source protocol whose purpose is to allow different Tightening Devices brand to connect and work together.

DeMeter uses Open Protocol to connect then retrieve Tightening results. In that particular setup, DeMeter is the Client, i.e. it will connect to the target tightening device who acts as a server.

However, a minimum number of MIDs must be available for DeMeter to be able to retrieve the tightening results.

The next sections will list the MIDs being necessary to ensure:

• DeMeter connects to the target device.
• DeMeter retrieves tightening numerical results (real time and off-line).
• DeMeter retrieves tightening curves.

2.1 - 概述

Open Protocol是一种开源协议，其目的是让不同品牌的拧紧装置能够相互连接并协同工作。

DeMeter使用开放协议进行连接，然后检索拧紧结果。在这种特定设置中，DeMeter作为客户端，即它会连接到作为服务器的目标拧紧设备。

然而，为了使DeMeter能够检索到拧紧结果，必须确保有最低数量的MID可用。

接下来的部分将列出为确保以下事项所必需的MID：

DeMeter连接到目标设备。

DeMeter可获取紧固数值结果（实时和离线）。

DeMeter可检索拧紧曲线。

Note: DeMeter can not retrieve tightening results via Open Protocol from Multi-spindle devices.

注意：DeMeter无法通过开放协议从多主轴设备获取拧紧结果。

The target asset must be compatible with the following MIDs handling Open Protocol connections - note that DeMeter will always try to connect with the higher MID revision, then work its way down if the target device reject the mid revision.

2.2 - 连接与通信MID的要求

目标资产必须与以下处理开放协议连接的MID兼容——请注意，DeMeter将始终尝试连接更高版本的MID，如果目标设备拒绝该MID版本，则会尝试连接较低版本的MID。

DeMeter can retrieve real-time results and also older results from the controllers. Both behaviors require the target asset to support 2 different sets of specific MIDs.

DeMeter可以检索实时结果，也可以从控制器中检索旧结果。这两种行为都要求目标资产支持两组不同的特定MID。
