| Comms Speed |
Internal Parameter, Read-write, Enumerated (signed 16-bit integer) 0 = 300 b/s 1 = 600 b/s 2 = 1200 b/s 3 = 2400 b/s 4 = 4800 b/s 5 = 7200 b/s 6 = 9600 b/s 7 = 14.4 kb/s 8 = 19.2 kb/s 9 = 28.8 kb/s 10 = 38.4 kb/s 11 = 57.6 kb/s 12 = 76.8 kb/s 13 = 115.2 kb/s |
| Comms Configuration |
Internal Parameter, Read-write, Enumerated (signed 16-bit integer) 0 = 8-N-1 1 = 8-O-1 2 = 8-E-1 3 = 8-N-2 8-N-1 : 8 data bits, No parity, 1 stop bit; 8-O-1 : 8 data bits, Odd parity, 1 stop bit; 8-E-1 : 8 data bits, Even parity, 1 stop bit; 8-N-2 : 8 data bits, No parity, 2 stop bits |
| Actual Polling Period |
Internal Parameter, Read-only, Analog (signed 16-bit integer) 0 ms to 32767 ms 32767 = >30s |
| Comms Timeout |
Internal Parameter, Read-write, Analog (signed 16-bit integer) 0 ms to 30000 ms this value is added to the computed comms time (based on comms speed) to determine when a comms transaction will time out. |
| Comms Sleep Time |
Internal Parameter, Read-write, Analog (signed 16-bit integer) 0 ms to 30000 ms 0 = Disabled Can be used to add “deadtime” to the comms polling cycle |
| Status |
Output, Read-write, Enumerated (signed 16-bit integer) 0 = OK 1 = Error This is the logical inclusive-OR of all the ‘Last Error’ parameters in the Register function blocks. It is updated once each poll. Resetting this parameter also resets ALL the ‘Last Error’ parameters. |
| Enable |
Input, Read-write, Boolean (signed 16-bit integer) 0 = Disable 1 = Enable |
