OPC 40082-3 covers the following functionalities:
- General information about the LSR dosing system
- Status information
- Process data
If multiple LDS are operated alternately on one machine for the same injection unit (see Figure 1), one system must act as the Master. This Master provides the regular OPC UA server. The Master server always provides the data of the active system in the network. The direct operation of several LDS servers between machines and LDS is not scope of this specification.
More information is listed in Table 1.
