+===== Rocrail Service tab. =====
+{{rocrailini-service-en.png?800}}\\
+ \\
+===== HTTP Service =====
+[[servermonitor-en|See for details this chapter.]]
+ \\
+====Port====
+:!: The port must differ from the client service port to avoid conflicts.\\
+ \\
+===== Clock Service =====
+Use this service if a faster clock is wanted and/or all clients must be synchronized.
+====Divider====
+The time divider is used to setup the clock speed: 1...100. (Example: A divider of 10 will run the model time 10 times faster than real time.)\\
+The next field is the Client update frequency in model minutes: 1...60. Default is every model minute.\\
+====Hour/Minute====
+This is the start time for the clock service.\\
+The computer time is used if the values are set to 24:60.\\
+====Semi real time====
+With this option all fast clock options are available if the divider is set to one. (Otherwise clock commands are rejected.)\\
+__Note:__ //The clock will no longer be in sync with the hardware computer clock.//\\
+====Stop clock at power off====
+Stop the fast clock in case of a power off event. (Short cut)\\
+ \\
+===== Client Service =====
+This is the port at which Rocview clients must connect to become all data and events needed to function.
+==== Client Port ====
+The official assigned port by IANA is **[[iana-rcs|8051]]**. \\
+==== Only first can control ====
+Prevent secondary clients controlling the Rocrail server; only the first one connected has control.\\
+A better solution is the use of Control or Slave Code.
+==== Control code ====
+The client must provide this control code to get write access if set.\\
+  * This overrules the "Only first can control" option.
+  * Leave blank for normal use.
+  * Supported Mobile Clients:
+    * Rocweb
+    * andRoc
+ \\
+=====WIO Watchdog=====
+Enables monitoring of WIO reachability. The timeout ist defined in units of 10 ms.\\
+Default: 700 x 10 ms = 7 seconds.\\
+WIOs are sending every 4 seconds an alive message.\\
+====Exclude====
+Excluding none relevant WIOs can be done as CSV list with IDs.\\
+Ranges are also allowed like: ''45-55''\\
+ \\
+===== Slave code =====
+If the slave code is set, and a connected client **cannot** provide this code, the following selected features will be rejected:
+  * System (Includes automatic and power commands.)
+  * Shutdown Server
+  * Switches
+  * Signals
+  * Outputs
+  * Routes
+  * Locomotives
+ \\
+===== SRCP Service =====
+{{ :srcp-clients.png?300}}
+Optional service for **[[http://srcpd.sourceforge.net/|SRCP]]** Clients like **[[http://sourceforge.net/projects/j-man/|J-Man]]** or **[[http://spdrs60.sourceforge.net/|spdrs60]]**.\\
+The objects addressed by those clients must be defined in the Rocrail track plan.\\
+  * http://www.der-moba.de/index.php/Digitalprojekt#SRCP-Clients
+  * [[:srcp-scripting-en|SRCP scripting]]
+====Device====
+Optional serial device to service SRCP.\\
+Line settings are fixed:
+  * 115200 bps
+  * 8N1
+ \\
+===== SNMP Service =====
+Activates the **[[http://en.wikipedia.org/wiki/Simple_Network_Management_Protocol|SNMP]]** v1/2c Agent in the Rocrail server.\\
+:!: By default port 161 is used for the SNMP service which requires extra user privilege: \\
+<code>
+OSNMP    0658 SNMP bind
+OSocket  0513 bind() failed [13] [Permission denied]
+</code>
+ \\
+==== Config ====
+<code xml>
+  <SnmpService port="161" trapport="162" traphost="192.168.100.77"/>
+</code>
+==== GetRequest example ====
+Direct ObjectID:
+<code>
+$ snmpget -v 2c -c public localhost 1.3.6.1.2.1.1.1.0
+iso.3.6.1.2.1.1.1.0 = STRING: "Rocrail 2.0.2508 Sunrise"
+</code>
+Symbolic OjectID:
+<code>
+$ snmpget -v2c -c public localhost SNMPv2-MIB::sysDescr.0
+SNMPv2-MIB::sysDescr.0 = STRING: Rocrail 2.0.2508 Sunrise
+$ snmpget -v2c -c public localhost SNMPv2-MIB::sysUpTime.0
+SNMPv2-MIB::sysUpTime.0 = Timeticks: (3443) 0:00:34.43

+=====@Box=====
+The location of the __**[[:abox:archivebox-en|@Box]]**__.\\
+ \\
+=====MQTT Service=====
+Clients can use the __**[[http://mosquitto.org|MQTT Broker]]**__ to communicate with the Rocrail Server.\\
+^ MQTT Topic ^ Description ^
+| ''rocrail/service/info'' | All server broadcasts are published with this topic name. |
+| ''rocrail/service/client'' | Clients can publish commands with this topic. \\ :!: //A valid support key is necessary; Without key only 5 demo minutes. // |
+| ''rocrail/service/field'' | Clients can publish hardware events with this topic. |
+| ''rocrail/service/command'' | Command station commands for __**[[:digint:user-en|User Libraries]]**__. |
+\\
+The payload of the MQTT messages are in __**[[:rocrail-server-scripting-en|RCP Format]]**__.\\
+The Rocrail Server uses the __**[[http://public.dhe.ibm.com/software/dw/webservices/ws-mqtt/mqtt-v3r1.html|MQTT V3.1 Protocol]]**__.\\
+====Hostname====
+The DNS name or TCPIP address of the MQTT Broker.\\
+====Port====
+The service port number of the MQTT Broker.\\
+The default port number used by [[https://mosquitto.org|Mosquitto]] is 1883.\\
+====Group====
+//Topic grouping//\\
+Use the Item Names in the Broadcast Topic.\\
+====User CS Libraries====
+With both topics, //field// and //command//, it is possible to implement a user defined CS library without Rocrail Source dependencies.\\
+====Clients====
+Only __**[[http://public.dhe.ibm.com/software/dw/webservices/ws-mqtt/mqtt-v3r1.html#qos-flows|Quality of Service 1]]**__ is supported.\\
+Clients may use QoS 0, but we strongly recommend QoS 1.\\
+The only known Client for this service is the command line utility of Mosquitto:\\
+<code bash>
+mosquitto_pub -p 60123 -t rocrail/service/client -m "<sys cmd=\"stop\"/>" -q 1
+</code>
+Broker response:
