Format | Has no meaning on the server as |
| N/A |
|
| the driver responds based on the |
|
|
|
| nature of the request |
|
|
|
| The map descriptors should be |
|
|
|
| considered to be the definitions of |
|
|
|
| data tables in a PLC. Thus one map |
|
|
|
| descriptor can be used to respond |
|
|
|
| to bit or byte requests. |
