The Texmate ISM1 magnetostr ictive smart input module is designed to oper ate with most digital interf ace leading/trailing-edge pulse magnetostr ictive tr ansducers. These include the f ollowing man ufacturers of magnetostrictive transducers:
Balluff.
Gefran.
MTS Systems Corporation.
Novotechnik.
Patriot Sensors and Controls Cor poration.
SanTest.
TR Electronic.
As an example, the ISM1 magnetostr ictive smart input module, shown in Figure 1, interf aces directly with and supplies +24 V excitation voltage to a Balluff micropulse P-style magnetostrictive transducer. The ISM1 can be configured to receiv e either trailing-edge active (P Balluff option) or leading-edge activ e (M Balluff option) pulses.
Note, the ISM1 only suppor ts the P and M digital RS-422 output interf ace options.

All setup procedures are carr ied out b y Texmate pr ior to shipping. Customers are responsib le for pinout connections between the controller and the sensor.
Smart Setup Registers
Texmate have a range of smart input modules that require prog ramming through the controllers programming modes. The meter has three smar t setup registers a vailable to configure the installed smar t input module. Input module ISM1 requires only smar t registers 1 and 2 to be set up. The ISM1 input module is configured f or tr ailing/leading-edge activ e receiv ed pulses, sample r ate, n umber of magnet positions, required number of velocities, and setpoint controlled outputs.
Figure 2 shows the logic flow through the ISM1 smar t input module.

Macro Programming
Prior to shipping, Texmate configures the controller with a macro. The macro automates the prog rammable functions a vailable in the controller to perf orm our customers requested functions. The macro is programmed on a PC using Texmates in-house de velopment softw are prog ram, kno wn as the Tiger Development System (TDS) compiler program. The TDS compiler saves the macro as a.bas file that is then downloaded to the controller.
Tiger 320 Macro Overview The Tiger 320 Series of programmable meter controllers have been designed to incorporate the analog and digital functionality of an intelligent controller with the logic of a PLC.
Traditionally, the PLC approach is to build a working application entirely in some form of programming language. The approach used in the Tiger 320 Series of controllers is to b uild an application by selecting the pre-programmed functions of the controller and then adding small amounts of prog rammability and logic where needed.
The operating system of the Tiger 320 controller controls all the pre-prog rammed functions, handling the input, averaging, scaling, linear ization, totalization and m uch more, as w ell as dr iving the displa y, timers, relays, analog and ser ial outputs. Once configured, these functions are e xecuted by the operating system and form the basis of a control system.
To form an advanced automation and control system you only need to write a small program that adds the extra logic required. We call this program a macro. A macro can be wr itten specifically for your application and is used to initiate a sequence, reconfigure, or disable some of the controller functions. With Texmate's
22 I/O plug-in module installed, a macro fur ther expands the Tiger 320 oper ating system with additional digital status inputs and digital s witched outputs.
Custom Macro Programming
Texmates Tiger Development System (TDS) enables a macro to be wr itten and compiled in BASIC, utilizing any combination of the hundreds of functions and thousands of registers embedded in the Tiger 320 Operating System. When y our BASIC prog ram is compiled into Tiger 320 Macro-language it is error checked and optimized.
Macros are useful when implementing a specializ ed control system that cannot be achie ved by the standard configuration capability of the Tiger 320 Operating System. Using the TDS software, functions can be altered or added in a standard controller to perf sequencing functions and mathematical functions.
orm the required job. This ma y typically include logic
Developing a Macro is m uch easier and quicker than programming a PLC, because the basic code required to customize the Tiger meter is considerably less than the ladder logic prog ramming required for PLCs. This is due to the hundreds of functions built into the Tiger controller that can be manipulated or invoked by a macro to fulfill the requirements of almost an y application.
Scrolling display messages can be prog rammed to appear with an y setpoint activation, selected event, or logic input. Easy to read, plain text prompts can be programmed to replace the manual programming codes and provide a user-friendly interface for any custom application.

Scrolling Text Messaging
Scrolling text messaging is another bon us from r unning a macro. Any number of messages f or detailed operator instructions, of up to 100 char acters each, can be wr itten into the macro dur ing compilation f or detailed operator instructions, alarm and control applications.
A scrolling text message can be written for OEMs and sensor manufacturers providing informative instructions for setup and calibration procedures.
