Time is counted independently for each defined area (Slave
device) and reduces only the frequency of querying for areas
with communication errors.
Data type
- number
Range
- 1....65535 [s]
Default
value
15
[s]
Comments
- Increasing this value reduces influence of malfunctioning
devices on communication with other devices but decreases
statistic time to reestablish communication after removal of
error cause.
8.2.5.4.3. Data block 1...16
The table defining sequential data blocks read from attached to PORT2 peripheral
Slave devices allows defining of 1 to 16 independent blocks in one or more devices.
Consecutive blocks may encompass registers from different spaces and be refreshed
at different intervals.
8.2.5.4.3.1. Modbus ID of Slave device
Function
- Defines Modbus ID of Slave device from which configured data
block is to be read
Data type
- number
Range
- 0....255
Default
value
- 0
Comments
- setting Modbus ID to
0
(
zero
) switches the mapping off
8.2.5.4.3.2. Space
Function
- selects Modbus space mapped from peripheral Slave device
attached to PORT2
Data type
- selection list
Range
-
Bi In
Binary inputs (1xxx), read-only
Bi Out
Binary outputs (0xxx), read and write
Inp. Reg.
Input Registers (3xxx), read-only
Hold. Reg.
Internal Registers (4xxx), read and write
Default
value
-
Bi In
Comments
- writing into registers mapping read-only spaces does not cause
an error. Values will be replaced by next error-free reading
from peripheral device.
8.2.5.4.3.3. Address of mapped space in module
Function
- defines start address of internal register in the module, used
for mapping space from the Slave. For mapping space Internal
registers are always used.
