Chapter 5 Control Block and Status BlockScrEdit Software User Manual

The definition for each function and usage of Control Block and Status Block will be introduced in the following chapters.

5.1Control Block

HMI can be controlled via PLC by designating the register from control block settings. The register is a continuous data block and its length is from 0 to 8 WORD’s. The length is different depends on function. For example, it needs at least 7 WORD’s for recipe function. When the control block size is set to 0, the control block function is disabled. If the control block function is enabled, HMI can judge the operation that is commanded by the external controller by reading the setting in the control block rapidly and continuously. The function and explanation of each WORD are listed below. (In the following table, we assume that the user uses a Delta PLC, so the available starting addresses in control block are Dn ~ Dn+7 (D0 ~ D7).)
