*1 Cannot be set in this product.
*2 In TCP/IP connection, the module can be connected up to the number calculated by the following formula: (the maximum number of
connections in the setting for external device configuration) - (the number of connections whose communication methods are not
"MELSOFT Connection") + 1. When a device is connected via multiple connection routes, it is counted as one device for each
connection route. For MELSOFT products on a personal computer, each connected MELSOFT product is counted as one device even if
they are connected via the same connection route. (When connecting CW Configurator which runs on this product, it is also counted as
one device.)
*3 In UDP/IP connection, there is no restriction on the number of connections. However, because simultaneous communication from
multiple connected devices can overload network, communication may not be established in such overloaded network conditions.
*4 Own station port numbers 1 to 1023 are numbers for reserved in general (WELL KNOWN PORT NUMBERS), and port numbers 61440
to 65534 are numbers used for other communication functions. Using the port number within the range of 1024 to 4999 or 5010 to 61439
is recommended.
