9.2.2.2 Remote communicationMain menu/Settings/General settings/Communication/LDCM configuration/LDCMDisplays settings for Remote Binary Communication (CRB) and for Remote MultiCommunication (CRM). The multi communication block can send both binary andanalog data whereas the binary can only send binary data.Each instance of CRB has several settable parameters where the channel mode can beset on or off, terminal numbers can be entered, synchronization can be set to master orslave and opto power can be set high or low.Each instance of CRM has several settable parameters. These include those above andothers such as transmission delay and transmission current.9.2.2.3 SPA, LON and IEC 60870–5–103 settingsRear optical LON portThe menu for the rear optical LON port has five submenus for various settingsaffecting LON parameters. The HMI paths to these submenus and their contents aredescribed below.Main menu/Settings/General settings/Communication/SLM configuration/Rearoptical LON port/GeneralIn the General submenu there are three settings. These are for the Subnet address, theNode address and the NeuronID.Main menu/Settings/General settings/Communication/SLM configuration/Rearoptical LON port/ServicePinMessageIn this submenu a Service pin message can be generated. This is similar to a “ping” intraditional networks. This sends a signal to another node in the system which is thenmade aware of the Neuron ID of LON port and can respond to that port.Main menu/Settings/General settings/Communication/SLM configuration/Rearoptical LON port/ADEThe Application Data Event (ADE) menu is where operation of LON is set on or offand where the data exchange speed can be set. If LON is used primarily to send eventdata then the appropriate setting is slow. Should LON be used, for example, as achannel for TRIP signals then the setting fast would be appropriate.Section 9 1MRK506276-UUS BRead and change settings42Operator's manual
