Configuring Properties |
This topic contains information about the properties available on the BCM2_MasterSlave tab, also informing the value of Strings for offline properties, which can be programmed by users when starting an application in Offline mode. These Strings can be listed on a table, according to the next example.
In addition to the Properties Window, these settings can be defined at run time in Elipse E3, Elipse Power, or Elipse Water applications. To do so, start this Driver in Offline mode, that is, execute the application with its Start driver OFFLINE option enabled, which is configurable on the Setup tab of the Properties Window. The configuration options of this Driver are described on the next table.
Communication Settings
Option |
String |
Data Type |
Description |
|---|---|---|---|
Retry failed responses (time-out) |
BCM2_MasterSlave.RetryResponse |
Number |
Option to enable or disable the procedure of internal retries of this Driver to recover a response not yet received from a device (time-out). Possible offline values are 0: Disabled or 1: Enabled |
Number of retries |
BCM2_MasterSlave.NumRetries |
Number |
Defines the number of internal retries that this Driver must perform before considering a reading error |
Force reconnection after the last retrial |
BCM2_MasterSlave.ForceReconnect |
Number |
Option to enable or disable the procedure of disconnecting and reconnecting the communication layer with a device, after all internal attempts to recover responses by time-out have failed. Possible offline values are 0: Disabled or 1: Enabled |
SOE Settings
Option |
String |
Data Type |
Description |
|---|---|---|---|
Max. Number Of Events |
BCM2_MasterSlave.SOE.MaxEvents |
Number |
Maximum number of SOE events capable of being stored in a buffer by this Driver, in case of using the feature of timestamp readings via Sequencing of Events (SOE). This number must correspond to the size of the circular buffer kept by the PLC software. The default value of this option is 700 |
W3, W4, W5, W6/W7, and W8/W9 |
BCM2_MasterSlave.SOE.W3, BCM2_MasterSlave.SOE.W4, BCM2_MasterSlave.SOE.W5, BCM2_MasterSlave.SOE.W67, and BCM2_MasterSlave.SOE.W89 |
Number |
Address of PLC's internal variables, which must be kept to implement the Sequencing of Events (SOE) reading. For more information, please check topic Sequencing of Events |
All offline properties must be configured via PLC Tags in String format, by using the N1 parameter equal to -1 (minus one), the N2 parameter equal to 0 (zero), the N3 parameter equal to 0 (zero), and the N4 parameter equal to 3 (three). For more details and examples of the other tabs, please check topic Documentation of I/O Interfaces.
