The downstream devices should be addressed 1 to N where N is the number of devices, not to
exceed 20. See Figure 10

If devices are later added to the device chain,

t
he user’s administrator must increase the Modbus device count in SETUP, which causes
the Monitor to search its device chain to fill the increased device count; and
•
the Monitor will display the additional devices as generic device types, as in Figure 15,
until the administrator assigns them unique device names.
