Question:
Is there any way to add additional communications ports to a CLICK PLC?
Answer
There is not a way to add addition communications ports to the Click PLC.
All Clicks (except the C2-02CPU which has wireless only) have an RS232 port and depending on the model of Click, it can also have an additional RS-232, RS-485, Ethernet, or Wi-Fi port available on the CPU.

Question:
What is the SCCR rating for the CLICK PLCs?
Answer
Our PLCs are not power circuit components. The SCCR is not required for them. Please refer to UL508 177.1 and UL508A SB4.1 for details.
UL508 177.1 defines what the PLC is and UL508A SB4.1 covers the standard for the SCCR.

Question:
Why does the Click CPU keep asking for a firmware update, or says it has no firmware, but I update the fw and it doesn't accept the update?
Answer
Check your DC voltage to the Click CPU. This problem occurs when the voltage is below the nominal 24 VDC that the CPU requires.

Question:
In Software Version 1.40, I do not see an option to "display Modbus address" in the address picker. How can I fix that ?

Question:
Is it possible to connect out of the RS485 Port 3 on Click to one of the Advanced stepper drives ( 4850 or 80100)?
Answer
While it is possible, the cost and wiring issues make a 2nd Click a much easier solution.
Click Port 3:
+ to TX+ on ISOCON Term block D
- to TX- on ISOCON Term block D
GND to GND Term block D
1/2 Duplex dipswitches both on on bottom bank of ISOCON.
5V and 0V Bias dipswitches on as well.
Must power cycle ISOCON after dipswitches are changed.
ISOCON Port A Pin 4 (TX) to Pin 5 on 4850 drive (RX)
ISOCON Port A Pin 3 (RX) to Pin 3 on 4850 drive (TX)
ISOCON Port A Pin 1 to Pin 2 on 4850 drive (GND on both)NOTE: Do NOT use Pin 6 on ISOCON Port A. It is not the same potential as Pin 1, though the ISOCON manual shows them as being the same.

Question:
If I don't have a battery in the Click, will I lose the program?
Answer
All CLICK PLC units have a non-volatile FLASH ROM to store the downloaded ladder program and project file. The FLASH ROM will retain the ladder program indefinitely. You do not have to have a battery.
However, the Click data registers are stored in the SRAM (volatile) memory, that is backed up by a super capacitor. The super capacitor will hold the memory contents for a short period of time, like a power cycle.
Super Capacitor Data Hold Time
- For C0 Clicks (page 2-9 of the Manual )
- Non-Ethernet Click -> 7 days.
- Ethernet Clicks -> 1 hour.
- 1 hour
For C2 Clicks (page 2-5 of the Manual )
If you plan on having power off the Click for longer then the super capacitor can hold data, and want to retain the data memory, you will need to use the optional battery.
