| + The {{set}} node has type {{wr}}. This means |
| + that its value is written to the hardware as soon |
| + as it is changed and read back regularely (by default every 10 seconds). |

| + We have not yet explained how the host and port of the connection |
| + is specified. This is done by the following command: |
| + |
| + {{{ |
| + cfgenv tem psts231.psi.ch:3006 |
| + }}} |
| + |
| + In this command we tell the system to use host {{psts231}} and |
| + port 3006 for connecting a device called tem. This information |
| + is persistent in the SeaServer of the instrument. It should not |
| + be used in any script or configuration file, as these are shared |
| + by the different instruments. |
