should I write this as "N7:150" ? 

Thanks and kindly answer this question also 

So its mean below both packets have same address that is 0xA7 (167 dec). The only difference is one is using three bytes to represent address and the other uses only one. Format1:10 06 10 02 00 00 0F 00 41 00 A2 02 07 89 FF A7 00 00 10 03 3B 74 format2: 10  06  10  02  00  00  0F  00  03  9D  A2  02  07  89  A7  00  10  03  83  15 Allen bradly PLC and hmi is communicating on format 1 but the weintek HMI(that I want to replace with original HMI) is using format 2. will the plc accept packages from HMI(format 2 packages)   

this packet specifies "N7:255" and what if I want to expand this field to three bytes as shown in DF1 protcol manual: "Addresses elements 0- 254 only. For higher addresses, setting this byte to FF expands this field to three bytes. Use the second and third bytes for the expanded element address (low address byte first)." what values should I have to add or replace in "N7:255"   or make it simple to understand  Q: how to set element(150) in Expanded three byte?

Thanks for your help. i'm using 9-pin D-sub port (Df1 protocol) Actually I have a protected SLC 5/04. I may not be able to change anything inside PLC as it is protected. and want to replace defected HMI to weintek HMI. Orginal HMI send below packet  to SLC 5/04 to write  (fetch from serial monitoring) 10 06 10 02 00 00 0F 00 41 00 A2 02 07 89 FF A7 00 00 10 03 3B 74 Q: what address above packet want to read?   I designed a numeric  object on easy builder pro (see attachment:  "numeric_in_property.jpeg") and the packet send from weintek hmi to SLC 5/04 is. (see attachment:  "address_255_packet.jpeg")   10  06  10  02  00  00  0F  00  03  9D  A2  02  07  89  FF  00  10  03  83  15                                         Observations: both packets are same except address field  original HMI address contains: 3 byte addressing field  weintek HMI address contains: 1 byte addressing field  Q: how to set three byte addressing field in weintek object attributes? kindly help me so that I may be able to set proper settings and properties of weintek HMI properties so that required address can be read from plc. thanks    

10 06 10 02 00 00 0F 00 41 00 A2 02 07 89 FF A7 00 00 10 03 3B 74 this is the SLC5/04 protected type logical read. according to my knowledge,  02 07 89 FF A7 02=required byte 07=file number 89=integer type address=FF A7 The confusion is how to call that address in rslogic500/weintek HMI/advancedHMI  or any other. is that address is equal to" FF+A7=1A6 hex (422 decimal)" i write N7:422 but i causes an error am i taking this address right?  if not then what would be the right address for this I'm new in allen bradly, kindly help me out and sorry for my bad english
