Note

In MX OPC Server, the BOOL array tag is 1 bit per element.
(In DxpSERVER , BOOL array tag is 16 bits per element) When importing a BOOL array tag, convert it to cover all the devices with the BOOL type array tag set in MX OPC Server .

Example 1: MX OPC Server (before conversion): M7 Bool array size 15 Read range: M7 to M21 (15bit) DxpSERVER (after conversion): M0 Bool Array size 2 Read range: M0 to M32 (32bit)

Example 2: MX OPC Server (before conversion): D0.F Bool Array size 3 Read range: D0.F to D1.1 (3bit) DxpSERVER (after conversion): D0 Bool Array size 2 Read range: D0.0 to D1.F (32bit)
