Functional description
• When i_bEN (Execution command) is turned on, a command for enabling/disabling i_uVirtualInputPortState (Virtual input
port status) of i_uVirtualInputPortNo (Virtual input port number) is sent to the network camera. i_uVirtualInputPortState
cannot be automatically disabled once it has been enabled. Therefore, disable i_uVirtualInputPortState after the event is
started. If not disabled, the next event cannot be started.
• If the number of the set characters is outside the effective range for i_uConnectionNo (Connection number), i_sUsername
(User name), and i_sPassword (Password), o_bErr (FB completed with an error) turns on and the processing of the FB is
interrupted. In addition, the error code, C1E0H, is stored in o_uErrId (Error code). ( Page 54 Error codes)
• If the set value for i_uVirtualInputPortNo is outside 1 to 32, o_bErr turns on and the processing of the FB is interrupted. In
addition, the error code, C1E1H, is stored in o_uErrId. ( Page 54 Error codes)
• If no response is returned from the network camera after the command is sent, o_bErr turns on and the processing of the
FB is interrupted. In addition, the error code, C1E2H, is stored in o_uErrId. ( Page 54 Error codes)
• If an unregistered i_sUsername or i_sPassword is set, o_bErr turns on and the processing of the FB is interrupted. In
addition, the error code, C1E3H, is stored in o_uErrId. ( Page 54 Error codes)
• For errors that occur in each processing for data communication between the Ethernet-equipped module and external
device, and errors that occur in processing requests from the CPU module in the own station, refer to the following.
