## System description
Presently there are two instances of EPICS IOC Server implemented.
Presently there are two/three instances of EPICS IOC Server implemented.
One responsible for the Temperature Node.
And a second one, installed in a Raspberry Pi, implemented in the new control unit launched at ISTTOK for the remote control of the vacuum pumps, named Central Node.
A third one is dedicated for readind the Vacuum Sensore through the RS484 Interface

#### Software Platform
[//]: # (This may be the most platform independent comment)
##### Start the IOC on power up
1. Make sure `screen` is installed in Linux
2. Include following Line in /etc/rc.local
* `screen -dm bash -c "cd [..]/ISTTOKrpi/iocBoot/iocISTTOKrpi; ../../bin/linux-arm/ISTTOKrpi st.cmd"`
3. To access EPICS console run
* `sudo screen -r`
1. Linux Raspian "buster" (user :pi):
* IP addr: 192.168.1.120 ( ISTTOK private network)
* NTP/timedatectl time conected to IPFN Gps NTP/PPS server IP:10.136.227.237 193.136.136.129
(this is mandatory, Rpi does not have a Real Time clock see https://www.raspberrypi.org/forums/viewtopic.php?t=178763)
* EPICS 7. To install follow [EPICS Docs](https://docs.epics-controls.org/projects/how-tos/en/latest/getting-started/installation.html)
