Chapter 5  Control Block and Status Block|ScrEdit Software User Manual

5.2 Status 
Block 
For two-way communication and display screen between DOP series and all brands’ PLC, it needs to input 
starting address of response register in status block. The status block in DOP series HMI is a continuous 
data block, such as Dm=D10 (length is 8 WORDs = D10-D17). When the control block size is set to 0, the 
control block function is disabled. If the control block function is disabled, the status block function is also 
disabled. When the status block function is enabled, the external controller, i.e. PLC can know the status of 
HMI by writing the setting in status block. But, please note that the address of control block and status block 
cannot be the same. 
The function and explanation of each WORD are listed below. (In the following table, we assume that the 
user will use a Delta PLC, so the available starting addresses in control block are Dm ~ Dm+7 (D10 ~ D17).)
