Hardware and Installation User Manual
1.2.1
Program Software
The TI525/TI535 PLCs are programmed in standard relay ladder logic, and
TISOFT programming software provides a means of entering, debugging, and
documenting your RLL program. TISOFT is menu-driven, provides both RLL
and advanced program special functions language, and permits you to add
comments to instructions. Different versions of TISOFT are available.
TISOFT1
operates on the VPU200; TISOFT2
is executed on an IBM PC/XT,
and TISOFT3
runs in an off-line mode on a DEC VAX computer.
You may also fully program the TI525/TI535 in Boolean symbolic code using the
Handheld Intelligent Terminal.
In addition to the standard relay ladder logic, the TI525/TI535 programming
instruction set offers more than 30 high-level, user-oriented operations. The
box instructions replace programming steps that once required hundreds of
words of memory. More importantly, these instructions permit you to use the
power of the PLC to perform complex functions, which makes program
development and debugging faster and easier.
1.2.2
Program Storage in EEPROM
The TI525/TI535 PLCs offer the option of saving your RLL program in a
non-volatile form by downloading it to an Electrically Erasable Programmable
Read Only Memory (EEPROM; PPX:2587681–8020) integrated circuit. A
separate programming device is not necessary. Once programmed, an
EEPROM may be removed and used in any of the TI525/TI535 or SIMATIC
TI530T
models, provided the program is compatible with the system’s
capabilities.
An EPROM may also be used to execute a program in a TI525 or TI535 PLC. The
program must be copied from an EEPROM described above or by an EPROM
programmer before it is installed on the TI525/TI535 CPU board.
To ensure equipment compatibility use only the EPROM model supplied by
your distributor: (PPX:2587681–8012).
