| Specifications |
| Digital input/output |
| Digital type | 5 V TTL input / CMOS output |
| Number of I/O | 4, configured as 3 ports of 8 bits each (Port 0, Port 1, Port 2) |
| Configuration | ach bit can be independently configured for input or output |
| Pull-up configuration | Each port has 47 k? resistors configurable as pull-up (default) or pull-down via internal jumpers W3 (port 1), W4 (port 2), and W5 (port 0). |
| Digital I/O transfer rate (system-paced) | 100 to 5000 reads/writes per second, typical, on a local network |
| Alarm functionality | Any combination of DIO bits may be configured to become outputs and go to defined values when an Ethernet connection with a host is established or lost. |
| Power on and reset state | All bits are input unless the alarm functionality is enabled for them. |
