| Fbus |
Built-in COM2 Port to exchange data between ICP DAS's ISaGRAF PACs. |
| Ebus |
To exchange data between ICP DAS's ISaGRAF Ethernet PACs via Ethernet port. |
SMS:
Short Message Service |
One COM port (one of COM1 or COM3 or COM4) (*) can link to a GSM modem to support SMS. User can request data/control the controller by cellular phone. The controller can also send data & alarms to user's cellular phone.
Optional GSM modems: GTM-201-RS232 (GSM/GPRS 850/900/1800/1900) |
| Modem Link |
Supports PC to remotely download & monitor the controller through COM4 of X504. (*) |
| MMICON/LCD |
The COM3: RS-232 (*)supports ICP DAS's MMICON. The MMICON is featured with a 240 x 64 dot LCD and a 4 x 4 Keyboard. User can use it to display picture, string, integer, float, and input a character, string, integer and float. |
| Optional I/O Functions (Refer to ISaGRAF PAC I/O Selection Guide for I/O Module list) |
