OPC UA服务器–服务请求–启动此功能启动OPC UA服务器。如果OPC UA服务器配置文件和证书已清除或尚未生成，则在服务器启动时生成。如果存在以前的配置文件和服务器证书，则使用它们时不会更改。服务器启动过程还将存储在控制器上的所有已发布变量添加到服务器的地址空间，直到变量和元素计数限制。START功能服务请求功能块的参数为：如果SVC_REQ未通电，则操作未完成。时区偏移调整OPC UA服务器时区。控制器的每日时间（TOD）时钟必须与当地时间同步，时区偏移是您所在位置相对于协调世界时（UTC，以前称为格林威治标准时间或GMT）的偏移。

OPC UA Server – Service Request – START This function starts the OPC UA server. If the OPC UA server configuration files and certificates have been cleared or have not yet been generated, they are generated when the server starts. If previous configuration files and server certificates exist, they are used without change. The server startup process also adds all published variables stored on the controller to the server’s address space, up to the variable and element count limit. Parameters for the START function service request function block are:If the SVC_REQ does not pass power, the operation did not complete. The time zone offset adjusts the OPC UA server time zone. The Controller’s Time of Day (TOD) clock must be synchronized to local time and the time zone offset is your location’s offset relative to Universal Time Coordinated (UTC, formerly known as Greenwich Mean Time or GMT).
