5 1 General This document describes the functions and object types of the Insertion Device. The systems, components and other objects that are controlled and/or supervised by Tango or PLC system are all denoted as objects in this document. Although, many functions are specified, this shall not be interpreted as if this document covers all functions in PCMS. 1.1 Expressions and phrases Explanations of, in this document, occurred expressions and phrases are described in the document Maxiv, Rules & Guidelines. 1.2 Locations

6 Description 1.3 Abbreviations and terms PLC Programmable Logical Controller 1.4 Function The PLC system is a part of the control system. There are several PLC:s installed at MaxIV. Each PLC are connected to modules which receives and send signals. For example, a valve will send signals to PLC if it is opened or closed. PLC will send signals to valve to open or close. A signal can be either logical (digital false or true), or more complex for example, reading a temperature. PLC systems are connected to networks where they communicate with the monitoring system Tango. Tango will both read status on signals and send commands. NOTE - VAC PLC system includes functionality for WAT and VNT but there are PLC systems for PSS, WAT and MAG. Those other systems are described in other documents. This document only covers VAC PLC system.

7 System Description VAC PLC 1.5 Parts PLC Many kinds of Rockwell PLC units are used. If there is a red unit it indicates that a safety part is included.

8 System Description VAC PLC Point IO Pont IO s are connected via Ethernet to the PLC. If there are red units it indicates they are safety units. 1.6 Network Two different networks are used to connect PLC s and Point IO. There is a Green network and a Blue network. They are easily recognised by the colour of the network cables. A PLC or point IO can only be connected to one of the two networks.

9 For the VAC system the PLC s are connected: BLUE NETORK B107A Flexpes B107A_A100730_CAB02_PLC01 B108A Species B108A_A100830_CAB03_VAC_PLC01 B110A Arpes B110A_A101030_CAB02_ VAC_PLC01 B111A MaxPeem B11A_A101130_CAB02_ VAC_PLC01 B112A Finest B112A_A101230_CAB01_ VAC_PLC01 GREEN NETWORK Linac I_B080603_CAB02_VAC_PLC GeV Ring R1- B080603_CAB02_VAC_PLC01 3 GeV ring ID- R3_B080603_ID_PLC01 3 GeV ring R3-B080603_CAB02_VAC_PLC01 3 GeV ring R3-B080603_CAB02_VAC_PLC02 B303A NanoMax B303A_A100330_CAB03_ VAC_PLC01

11 1.7 Control Bypassing Alarms All alarms created in the PLC system can have a bypass function. System owner must decide which alarms should have the bypass function. If an alarm is bypassed, the PLC system will disable the alarm, and the control- and monitoring system will not get any indication that the alarm is active. If system contains bypasses alarms PLC system sets a bit BYPASS EXISTS Bypassed alarms will stay bypassed until a decided time of the day. At the moment it is 12:13. When that time is reached all bypassed alarms will be enabled again. PLC system will set a bit BYPASS WARNING, at every decided interval. How many hours between these intervals will be entered in Tango. 60 minutes before time of day when bypassed alarms will be enabled, PLC system set a bit BYPASS EXPIERING. This is to indicate to operators that within 60 minutes alarms can affect operation. When PLC system has set the bit BYPASS EXPIERING, the operator can through Tango, decide that enabling of all bypassed alarms will not take affect this day. Then the enabling of all alarms will postpone to the following day. There is a maximum number of bypasses per group that can be done. A group can be valves, thermocouples, screens or other parts of the system. If operator tries to bypass more than allowed, an alarm will be set from PLC system. The maximum number of allowed bypasses per group is set from Tango Bypass Alarms Comment PLC code Ex from NanoMax Bypass tag: B_B303A_FE_DIA_TCO01_BYP_C alias N_B303A_FE_DIA_BYPASS_HB.0 (bit 0) N_B303A_FE_DIA_BYPASS_HB alias N_B303A_BYPASS_HB[1] element 1 in array. The N_B303A_BYPASS_HB[1] is a group. In Tango you enter max bypassed per group. N_B303A_VAC_PLC01_BMC_C = #T Max number of bypassed alarms per group. BYPASS ALARM HELPER will loop through all N_B303A_BYPASS_HB elements. NOTE default it loops through 20 elements. If you use more you have to increase the loop value. Time of the day when bypassed alarms will be disabled, is located in N_EXPIRY_TIME_ARRAY[0] hours and N_EXPIRY_TIME_ARRAY[1] minutes Hardware Control The PLC system has an integrated check of all hardware. That includes the point IO s that is connected to the PLC. If a fault is present, the PLC stores a fault code. If a fault code is present, an alarm will be raised in Tango. If it is an alarm from a point IO, it is a summary alarm. This means that the alarm will tell what point IO has a fault but not which module in the point IO. The PLC set an individual internal bit for each module that has a fault. This will not generate an alarm but can be used as an interlock in the logic.

12 Hardware Control Comment PLC code Point IO check is done in a separate periodic task, Node Checker. It runs every 50 ms. Main PLC is checked for faults in main task program SD card SD Secure Digital card is installed on each PLC. Most values that can be changed in Tango are stored on the SD-card. When values are changed in Tango they are stored automatically. Typical values are alarm limits for pressure or temperature. When PLC starts up it moves stored values from SD card to internal memory areas. This means that if a PLC has to be changed the SD card is moved to the new PLC. When new PLC starts it will get all stored values SD card Comment PLC code Use the excel file SD Read and write Code Generator to automatically generate the code needed. 1.8 Locations PLC systems are mounted in cabinets 1.9 Interfaces MAX IV PLC / Control System interface definitions The AllenBradley/Rockwell PLCs are maintained by the PLC Automation group and the TANGO control system is maintained by the Control System group. Communication between the PLCs and TANGO takes place via an RSLinx OPC server. This document defines the interface details, conventions and responsibilities between the groups Division of responsibilities Configuration of PLCs PLC Automation group Rockwell software updates (RSLinx etc) PLC Automation group OPC configuration Control System group OPC TANGO device server Control System group Maintenance of computer running OPC server Control System group Comment: The software license for RSLinx needs to be locally installed since the OPC server must be on the green net which has no internet access. The Control System group should be notified before updates are installed Naming convention Tags used in the TANGO control system shall be distinguished by prefixes: A_ alarms C_ commands R_ read S_ set Tags that control equipment states should be set up as pairs: OPEN and CLOSE tags (for example to control a valve) or START and STOP, INSERT and EXTRACT tags. For equipment states there should also be separate status tags (read tags) using the state in the name: CLOSED (STOPPED, INSERTED) OPENED (STARTED, EXTRACTED)

13 1.9.4 PLC status device server Status information for the PLC itself will be displayed in a TANGO device server and available through the control system. IP-address Firmware version Error counters Etc

14 2 Object types 2.1 Hardware Point I/O Object type: Node Checker, Type 1 Description: The point I/O node and all I/O modules sends a DINT value back to the system to indicate status. If value is below or greater than the module has a fault. Interlock To indicate that there is a module fault. A faulty module will also give wrong indication on connected I/O s.

Reset Error Node Checker, Type 1 Interface: Type Signal Id Description DI I_MODULE_OK If value between set bit OK for each node DO O_INTERLOCK If all nodes are OK output is FALSE

15 2.2 SD Read and Write Object type: Read/Write, Type 1 Description: Set points that can be set by HMI is stored on a SD card in the PLC. If a new value is changed the HMI sends a signal to PLC to store all value to the SD card. PLC reads all stored values from SD card at first scan. This is to get set points if PLC has to be changed or program needs to be updated. At first scan PLC sends command to open up SD card for reading. If SD card is ready, it will send back ok. If not O_ALARM_01 will be active. If reading cycle takes more than 15 seconds O_ALARM_02 will be active. The store bit is set by HMI. When PLC reads this bit it sends command to open up SD card for writing. If SD card is ready, it will send back ok. If not O_ALARM_01 will be active. If writing cycle takes more than 40 seconds O_ALARM_02 will be active. Alarms/events: Alarms The following alarms exist: Write cycle has failed Read cycle has failed SD card cannot be detected If alarm is disabled HMI: Indications Alarm status Manoeuvres Disable Alarm. Reset Alarm SD Card, Type 1 Interface: Type Signal Id Description DI I_START_WRITE Command sent from HMI to store new values on SD card DI I_START_READ First scan on PLC will all values AO O_ALARM_COUNT Count amount of alarm to be sent to be HMI DO O_ALARM_01 The SD card is not detected.
