CIMPLICITY1. ADV_PID: Ethernet Global Data
Each system wide PPS function block broadcasts a portion of its instance data onto the Ethernet global data highway. This data is used to interface with the function block from an HMI station in order to monitor and control a process system.
The Ethernet global data for the PPS advanced PID block is as follows.
| Global Data | Data Type | Description |
|---|---|---|
| FC | UINT | Faceplate Command |
| KD | REAL | Derivative Time |
| KI | REAL | Integral Reset |
| KP | REAL | Proportional Gain |
| ON | REAL | Minimum OP |
| OP | REAL | Controller Output |
| OX | REAL | Maximum OP |
| PI | REAL | Process Variable Indication |
| PN | REAL | Minimum PV |
| PX | REAL | Maximum PV |
| SC | REAL | Controller Setpoint |
| SK | UINT | Setpoint Tracking Switch |
| ST | DWORD | HMI Status Word |
