Re: Panel Builder 1400e Software 15

Sorry to bring up a dead thread - but I was just searching for this issue - "error with no text - panelbuilder 1400e install" and I was able to resolve this by reading the README and using the serial number found in the txt file.
In my example, on one specific page I need to display 18 integer variables to the operator. In order to get that much data into the PVe via RIO and still only use a single rack, I have to turn to Block Transfers.
In the picture below, you can see several block transfers are configure in my PanelBuilder 1400E project. Each line in the table reserves a byte of data in Rack 3 for the corresponding block transfer:
With the PanelView 1400E on Data Highway Plus you typically have tags which directly access your PLC-5 data table addresses. So, in place of the RIO tag list shown above, you would have tags like Start, Setpoint, and Speed pointing directly to addresses like B3:0/1, F8:0, N7:0.
Answer, part 1: If you have a 16 slot 1771 chassis setup as 2 slot addressing, then every two physical slots would share one Modular I/O Group. Therefore sixteen physical slots would make up 8 modular I/O groups, which is also one logical rack. (8 groups = 1 rack)
Answer, part 2: To use 16 point I/O modules in a 1771 chassis setup as 2 slot addressing (i.e. every two slots share one modular I/O group) then you need to alternate your Input and Output I/O modules. Or, if you only had input modules (or only had output modules) you would need to skip every other module. This is because in two slot addressing every two slots share a single modular I/O group, and each group ONLY has 16 input bits and 16 output bits.
Answer, part 2: To address an input or output we only need Rack, Group, and Bit. And address I:034/02 references the input word of rack 03, group 4, and bit 02. However, when we use Block transfers, which multiplexes many words through a single byte, we need to specify the rack, groups, and low or high byte to use. The low byte is represented by Slot 0, and the high byte is represented by slot 1.
I have 7 parameters on the PV that are controlled by Tag_DI13_7_0-7_7_Bin which has the address I:137/00-7/07 which makes sense bacause it is 8 parameters inputs. What does I:137/00-7/07 represents? The 8 parameters are 3 digit decimal number or integer so it has to be some sort of 8-16 bit address representation of this number in the PLC?

hello Shawn, in panel builder i have 4 files assigned for rack 13. 2 read 32 words each both through low and high of group /word 0 and 2 write 32 words each through low and high byte of group/word 0. while in Rslogix 5 i have only BTR that assigned to rack 13 group and module 0 for length of 32 and BTW assigned to rack 13 with group amd module 0 for length of 32 . Question: there is 4 files with size of byte each in PV software how does 2 block transfer write and read in RSlogix distinguish between low and high byte being transfered? the only thing that i can add is that each block has on its rung BT. EN bit from its own block and BT.EN from the other block. both of these bits XIO. this could be the answer to how they destinguish when reading from high or low byte of the group but i dont understand how. thank you
