1. What Are the Operating Environment Specs On TRi PLCs?
| Temperature - Operating - Storage |
0 to 70 degree C. -20 to +85 degree C |
| Electrical Noise resistance IEC801-4 (Fast transient) |
2KV to power supply, 50 microsecond pulse width, 1 minute. 1KV to I/O by capacitive coupling, 50 microsecond pulse width, |
| Vibration resistance IEC 68-2-6/1980 |
Vibration 1.6mm 25Hz to 100Hz Amplitude = +1. acceleration = + 4.0g |
2. Do TRi PLCs Have UL or CE Approval?
All TRi PLCs carry CE marking for conforming to the requirement of provision s in the EMC Directive 89/336/EEC as amended by 92/31/EEC, 93/68/EEC and 93/97/EEC.
As TRi PLCs operate below the current threshhold stipulated for UL Class 2 device, it does not need UL listing and approval for safe operation. This has no impact on the equipment that require UL certification since many of our PLCs have already been deployed in equipment and machinery that have undergone UL certification.
3. Can I Do Floating Point Computation on My PLC?
Yes the new Fx2424 and Fx1616-BA as well as customized PLC made with the SmartTILE all support IEEE754 single-precision floating point computation. i-TRiLOGI version 7 is required to write program using floating-point variables and math.
The FMD series (and M-series), and Nano-10 PLCs only compute using 32-bit integer arithmetics and do not support floating point computation. They are only programmable using i-TRiLOGI version 6 software.
Note that many computational task that seems to involve floating point math can also be handled using "fixed point" math, in which case a unit integer represents, say 0.01, and since a 32-bit integer can represent numbers of up to +/- 2 billion you can get a lot of fractional arithmetics computation done this way.
4. How Do I Select the Right TRi PLC to Meet My Need for I/Os, Timers Counters etc?
You can check the selection chart for each PLC family for an overall view of the number of digital I/Os, analog I/O, serial/Ethernet comm ports, etc available to the PLCs. Then go the "Product Home" page and select the respective PLC family and then select the PLC model of interest for viewing.
We have made all hardware manuals available online for all the PLC and peripherals, including installation guide, user manual, programmer's reference etc. So be sure to find them when you browse the detail for each PLC model.

5. What's the Difference Between a PAC (Programmable Automation Controller) and a PLC (Programmable Logic Controller)?
PAC was a newly coined term in the last few years to describe more sophisticated controllers that share the same hardware architecture as the 'Win-Tel' PC. These PAC were better equipped in terms of capability than traditional microcontrollers. They often operated on more advanced microprocessors and programming languages. Even though the TRi F-series, FMD series (and M-series), and Nano-10 'Super PLCs' are not based on PC architecture, they do, however offer lots of features that are found in a typical PAC and suit the control needs for many different industries.
