Hi Petr, What do you have a S5-155U or a S5-115U..... Normally you have to look in the handbook of the appropiated CPU, this because the different CPU's are not the same in the ISTACK. For example the CPU 941...944 have another ISTACK then the CPU 945, the other CPU's from the S5-155U with the CPU 946/947 or the CPU 948 are also other ISTACKs because that are WOrd CPUs. So look in one of the next Handbooks CPU 941...944, CPU 945, CPU 946/947, CPU 948.... When you look for example in the handbook of the CPU 941...944 on page 5-5 and further then you may find it for the PC/PGs: ISTACK Display on the PG 635/670/675/685/695 and 750 Tables 5-3 and 5-4 show the ISTACK as it is displayed on CRT-based programmers. Relevant information for the S5-115U is in bold print.BST-STP: is te place + 2 where the command is, if you use edit on the bottom then you go directly to the STOP-place, BEF-REG: is the command where the CPU stops with, see on the end of the handbook all hexadecimal commands. |
