Table 5-6. Maximum Number of IEC Tasks
Notes:
Values:
The number defined for each task type represents the maximum values allowed.
WHSB Task:
WHSB is a system task that must be considered so the total value is not surpassed. For
a redundant RTU profile, the user may create also the ProtTask, thus getting up to 2 cyclic tasks.
NET (n) – Client or Server Instances:
“n” represents the Ethernet interface. The maximum value
defined by system Ethernet interfaces, including the expansion modules when these are applied. E.g.,
MODBUS protocol instances.
COM (n) – Master or Slave Instances:
“n” represents the serial interface number. Even with
expansion modules, the value shown on the table will be the maximum per interface. E.g., MODBUS
protocol instances.
Total:
The total value does not represent the sum of all profile tasks, but the maximum value allowed
per CPU. Therefore, the user can create several task types, while the established numbers for each
one and the total value are not surpassed.
