Functional description

• When FB_EN (Execution command) is turned on, the time is set by sending the command of the CPU module time to the

network camera.

• If the number of the set characters is outside the effective range for iw_ConnectionNo (Connection number), is_UserName

(User name), and is_PassWord (Password), FB_ERROR (FB completed with an error) turns on and the processing of the

FB is interrupted. In addition, the error code, C1E0H, is stored in ERROR_ID (Error code). ( Page 96 Error code)

• If no response is returned from the network camera after the command is sent, FB_ERROR turns on and the processing of

the FB is interrupted. In addition, the error code, C1E2H, is stored in ERROR_ID. ( Page 96 Error code)

• If an unregistered is_UserName or is_PassWord is set, FB_ERROR turns on and the processing of the FB is interrupted. In

addition, the error code, C1E3H, is stored in ERROR_ID. ( Page 96 Error code)

• 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.

The value is a reference value because of the number of steps in the label program. For details, refer to the following.

• When a single FB (this FB) is used, the amount of label usage is as follows:

Word: 2.88K points

Bit: 0.03K points

• When two or more FBs are used, the amount of label usage is the sum of that of FBs used. For example, when two each of

FBs for time setting and FBs for recording direction are used, the amount of label usage is as follows:

Word: 2.88K + 2.88K + 2.78K + 2.78K = 11.32K points

Bit: 0.03K + 0.03K + 0.03K + 0.03K = 0.12K points

The usage of labels embedded in a program depends on the devices specified as an argument and the option settings of GX

Works2. For the option settings of GX Works2, refer to the following.

Since the amount of label usage of this FB is large, the number of word device points may become insufficient. In this case,

use the file register. For the settings of the file register, refer to the following.
