Wait_Flag	
This flag determines whether PLC will wait until the device serial ports receive the intended data before continuing. The request can either send a message and wait for a reply, or send a message and continue without waiting for a reply. If the Command Block specifies that the program will not wait for a reply, the Command Block contents are sent to the device and ladder program execution resumes immediately. This is referred to as NOWAIT mode. If the Command Block specifies that the program will wait for a reply, the Command Block contents are sent to the targeted device and the CPU waits for a reply for a maximum length of time specified in the Command Block. If the device does not respond in that time, ladder program execution resumes. This is referred to as WAIT mode.

Idle_Tmout	
The idle timeout value is the maximum time the PLC waits for the device to acknowledge receipt of the request. For NOWAIT, this value is not used. (Any timeout value is ignored; it can be zero.) If WAIT is selected, this word specifies the idle timeout period, in 100-microsecond increments.
#END# 

Max_Comm_Tm	
This word contains the maximum amount of time the program should hold the window open when the device is busy. For NOWAIT, this value is not used. (Any timeout value is ignored; it can be zero.) If WAIT is selected, this word specifies the maximum time in 100 microsecond increments.

Dev_Tasks
Download_Parameters Commreq block can send up to 16 Power Mate APM Parameter values at once. The total data length of the COMM_REQ must be set to 68 bytes (34 words). 
#END#

Download Parameters
Download_Parameters is used to send up to 16 Power Mate APM Parameter values at once. 68 byte data block will be required to be written. 
THE PARAMETERS HERE SPECIFIES THE DATA LOCATION WHERE USER HAS TO WRITE DATA. THIS IS NOT DONE BY THE THIS TOOL. 
In 68 bytes (34 words) data (located by memory type and zero based offset above) the first two data word must be Start Parameter Number (0-255) and Number of Parameter to load. Only the number of parameters specified in word offset 1 will be loaded into parameter memory. However, the 68 byte data block must always be initialized in the PLC. If the last parameter to be loaded is greater than 255, the COMM_REQ will be rejected.

Memory_Type_Of_Data
Memory Type for Data.

Memory_Offset_Of_Data
Memory_Offset_Of_Data: Location of data. Zero based Offset. For example use 205 for %R206.
