ABB SDCS-DSL-4-SET逻辑校验和字每次扫描要用作校验和算法输入的用户逻辑字的数量。有效范围：0到32760，增量为8。默认值：16。控制器通信窗口模式（仅当扫描模式设置为正常时可用。）控制器通信窗口的执行设置。选择：▪ 完成：窗口运行到完成。没有时间限制。▪ ABB SDCS-DSL-4-SET有限：时间限制。每次扫描的控制器通信窗口的最大执行时间在控制器ABB SDCS-DSL-4-SET通信窗口计时器参数中指定。默认值：有限。注：此参数对应于90-70系列PLC上的编程器窗口模式参数。ABB SDCS-DSL-4-SET

ABB SDCS-DSL-4-SET控制器通信窗口计时器（ms）（仅当扫描模式设置为正常时可用。仅当控制器通信窗口模式设置为完成时读取。）每次扫描控制器通信窗口的最大执行时间。此值不能大于看门狗计时器的值。

有效范围和默认值取决于控制器通信窗口模式：▪ 完成：没有时间限制。▪ 有限：有效范围：0到255ms。默认值：10。注：此参数对应于90-70系列PLC上的编程器窗口定时器参数

ABB SDCS-DSL-4-SETLogic Checksum Words The number of user logic words to use as input to the checksum algorithm each sweep. Valid range: 0 through 32760, in increments of 8. Default: 16. Controller Communication Window Mode (Available only when Sweep Mode is set to Normal.) Execution settings for the Controller Communications Window. Choices: ▪ Complete: The window runs to completion. There is no time limit. ▪ Limited: Time sliced. ABB SDCS-DSL-4-SETThe maximum execution time for the Controller Communications Window per scan is specified in the Controller Communications Window Timer parameter. Default: Limited. Note: This parameter corresponds to the Programmer Window Mode parameter on a Series 90-70 PLC.ABB SDCS-DSL-4-SET

ABB SDCS-DSL-4-SETController Communications Window Timer (ms) (Available only when Sweep Mode is set to Normal. Read-only if the Controller Communications Window Mode is set to Complete.) The maximum execution time for the Controller Communications Window per scan. This value cannot be greater than the value for the watchdog timer.ABB SDCS-DSL-4-SET

ABB SDCS-DSL-4-SETThe valid range and default value depend on the Controller Communications Window Mode: ▪ Complete: There is no time limit. ▪ Limited: Valid range: 0 through 255ms. Default: 10. Note: This parameter corresponds to the Programmer Window Timer parameter on a Series 90-70 PLC
